Greek fire was an incendiary weapon used by the Eastern Roman (Byzantine) Empire that was first developed c. 672. The Byzantines typically used it in naval battles to great effect, as it could continue burning while floating on water, it provided a technological advantage and was responsible for many key Byzantine military victories, most notably the salvation of Constantinople from two Arab sieges, thus securing the Empire's survival.

The impression made by Greek fire on the western European Crusaders was such that the name was applied to any sort of incendiary weapon, including those used by Arabs, the Chinese, and the Mongols. However, these were different mixtures and not the same formula as the Byzantine Greek fire, which was a closely guarded state secret. Byzantine use of incendiary mixtures was also used in pressurized nozzles or siphōns to project the liquid onto the enemy.

Although usage of the term "Greek fire" has been general in English and most other languages since the Crusades, original Byzantine sources called the substance a variety of names, such as "sea fire" (Medieval Greek: πῦρ θαλάσσιον pŷr thalássion), "Roman fire" (πῦρ ῥωμαϊκόν pŷr rhōmaïkón), "war fire" (πολεμικὸν πῦρ polemikòn pŷr), "liquid fire" (ὑγρὸν πῦρ hygròn pŷr), "sticky fire" (πῦρ κολλητικόν pŷr kollētikón) or "manufactured fire" (πῦρ σκευαστόν pŷr skeuastón).^[1][2]

The composition of Greek fire is unknown, it remains a matter of speculation and debate, with various proposals including combinations of pine resin, naphtha, quicklime, calcium phosphide, sulfur, or niter.

History[edit]

Incendiary and flaming weapons were used in warfare for centuries prior to the invention of Greek fire, they included a number of sulfur-, petroleum-, and bitumen-based mixtures.^[3][4] Incendiary arrows and pots containing combustible substances were used as early as the 9th century BC by the Assyrians and were extensively used in the Greco-Roman world as well. Furthermore, Thucydides mentions that in the siege of Delium in 424 BC a long tube on wheels was used which blew flames forward using a large bellows.^[5][6][7] The Roman author Julius Africanus, writing in the 3rd Century AD, records a mixture that ignited from adequate heat and intense sunlight, used in grenades or night attacks:

Automatic fire also by the following formula, this is the recipe: take equal amounts of sulphur, rock salt, ashes , thunder stone, and pyrite and pound fine in a black mortar at midday sun. Also in equal amounts of each ingredient mix together black mulberry resin and Zakynthian asphault, the latter in a liquid form and free-flowing, resulting in a product that is sooty colored. Then add to the asphalt the tiniest amount of quicklime, but because the sun is at its zenith, one must pound it carefully and protect the face, for it will ignite suddenly. When it catches fire, one should seal it in some sort of copper receptacle; in this way you will have it available in a box, without exposing it to the sun. If you should wish to ignite enemy armaments, you will smear it on in the evening, either on the armaments or some other object, but in secret; when the sun comes up, everything will be burnt up.^[8]

In naval warfare, the Byzantine Emperor Anastasius I (r. 491–518) is recorded by chronicler John Malalas to have been advised by a philosopher from Athens called Proclus to use sulfur to burn the ships of Vitalianus.^[9] Greek fire proper, however, was developed in c. 672 and is ascribed by the chronicler Theophanes to Kallinikos (Latinized Callinicus), an architect from Heliopolis in the former province of Phoenice, by then overrun by the Muslim conquests:^[10]

At that time Kallinikos, an artificer from Heliopolis, fled to the Romans [i.e., the Byzantines.] He had devised a sea fire which ignited the Arab ships and burned them with all hands. Thus it was that the Romans returned with victory and discovered the sea fire.^[11]

The accuracy and exact chronology of this account is open to question: Theophanes reports the use of fire-carrying and siphōn-equipped ships by the Byzantines a couple of years before the supposed arrival of Kallinikos at Constantinople.^[12] If this is not due to chronological confusion of the events of the siege, it may suggest that Kallinikos merely introduced an improved version of an established weapon,^[13][14] the historian James Partington further thinks it likely that Greek fire was not in fact the creation of any single person but "invented by chemists in Constantinople who had inherited the discoveries of the Alexandrian chemical school".^[15] Indeed, the 11th-century chronicler George Kedrenos records that Kallinikos came from Heliopolis in Egypt, but most scholars reject this as an error.^[16] Kedrenos also records the story, considered rather implausible by modern scholars, that Kallinikos' descendants, a family called Lampros, "brilliant", kept the secret of the fire's manufacture and continued doing so to Kedrenos' time.^[14]

Kallinikos' development of Greek fire came at a critical moment in the Byzantine Empire's history: weakened by its long wars with Sassanid Persia, the Byzantines had been unable to effectively resist the onslaught of the Muslim conquests. Within a generation, Syria, Palestine, and Egypt had fallen to the Arabs, who in c. 672 set out to conquer the imperial capital of Constantinople. Greek fire was used to great effect against the Muslim fleets, helping to repel the Muslims at the first and second Arab sieges of the city.^[17] Records of its use in later naval battles against the Saracens are more sporadic, but it did secure a number of victories, especially in the phase of Byzantine expansion in the late 9th and early 10th centuries.^[18] Utilisation of the substance was prominent in Byzantine civil wars, chiefly the revolt of the thematic fleets in 727 and the large-scale rebellion led by Thomas the Slav in 821–823; in both cases, the rebel fleets were defeated by the Constantinopolitan Imperial Fleet through the use of Greek fire.^[19] The Byzantines also used the weapon to devastating effect against the various Rus' raids on the Bosporus, especially those of 941 and 1043, as well as during the Bulgarian war of 970–971, when the fire-carrying Byzantine ships blockaded the Danube.^[20]

The importance placed on Greek fire during the Empire's struggle against the Arabs would lead to its discovery being ascribed to divine intervention, the Emperor Constantine Porphyrogennetos (r. 945–959), in his book De Administrando Imperio, admonishes his son and heir, Romanos II (r. 959–963), to never reveal the secrets of its composition, as it was "shown and revealed by an angel to the great and holy first Christian emperor Constantine" and that the angel bound him "not to prepare this fire but for Christians, and only in the imperial city". As a warning, he adds that one official, who was bribed into handing some of it over to the Empire's enemies, was struck down by a "flame from heaven" as he was about to enter a church,^[21][22] as the latter incident demonstrates, the Byzantines could not avoid capture of their precious secret weapon: the Arabs captured at least one fireship intact in 827, and the Bulgars captured several siphōns and much of the substance itself in 812/814. This, however, was apparently not enough to allow their enemies to copy it (see below), the Arabs, for instance, employed a variety of incendiary substances similar to the Byzantine weapon, but they were never able to copy the Byzantine method of deployment by siphōn, and used catapults and grenades instead.^[23][24]

Greek fire continued to be mentioned during the 12th century, and Anna Komnene gives a vivid description of its use in a naval battle against the Pisans in 1099.^[25] However, although the use of hastily improvised fireships is mentioned during the 1203 siege of Constantinople by the Fourth Crusade, no report confirms the use of the actual Greek fire. This might be because of the general disarmament of the Empire in the 20 years leading up to the sacking, or because the Byzantines had lost access to the areas where the primary ingredients were to be found, or even perhaps because the secret had been lost over time.^[26][27]

Records of a 13th-century event in which "Greek fire" was used by the Saracens against the Crusaders can be read through the Memoirs of the Lord of Joinville during the Seventh Crusade. One description of the memoir says "the tail of fire that trailed behind it was as big as a great spear; and it made such a noise as it came, that it sounded like the thunder of heaven. It looked like a dragon flying through the air, such a bright light did it cast, that one could see all over the camp as though it were day, by reason of the great mass of fire, and the brilliance of the light that it shed."^[28]

In the 19th century, it is reported that an Armenian by the name of Kavafian approached the government of the Ottoman Empire with a new type of Greek fire he claimed to have developed. Kavafian refused to reveal its composition when asked by the government, insisting that he be placed in command of its use during naval engagements. Not long after this, he was poisoned by imperial authorities, without their ever having found out his secret.^[29]

As Constantine Porphyrogennetos' warnings show, the ingredients and the processes of manufacture and deployment of Greek fire were carefully guarded military secrets. So strict was the secrecy that the composition of Greek fire was lost forever and remains a source of speculation.^[30] Consequently, the "mystery" of the formula has long dominated the research into Greek fire, despite this almost exclusive focus, however, Greek fire is best understood as a complete weapon system of many components, all of which were needed to operate together to render it effective. This comprised not only the formula of its composition, but also the specialized dromon ships that carried it into battle, the device used to prepare the substance by heating and pressurizing it, the siphōn projecting it, and the special training of the siphōnarioi who used it.^[31] Knowledge of the whole system was highly compartmentalised, with operators and technicians aware of the secrets of only one component, ensuring that no enemy could gain knowledge of it in its entirety,^[32] this accounts for the fact that when the Bulgarians took Mesembria and Debeltos in 814, they captured 36 siphōns and even quantities of the substance itself,^[33] but were unable to make any use of them.^[34][35]

The information available on Greek fire is exclusively indirect, based on references in the Byzantine military manuals and a number of secondary historical sources such as Anna Komnene and Western European chroniclers, which are often inaccurate; in her Alexiad, Anna Komnene provides a description of an incendiary weapon, which was used by the Byzantine garrison of Dyrrhachium in 1108 against the Normans. It is often regarded as an at least partial "recipe" for Greek fire:^[36][37][38]

This fire is made by the following arts, from the pine and the certain such evergreen trees inflammable resin is collected. This is rubbed with sulfur and put into tubes of reed, and is blown by men using it with violent and continuous breath. Then in this manner it meets the fire on the tip and catches light and falls like a fiery whirlwind on the faces of the enemies.

At the same time, the reports by Western chroniclers of the famed ignis graecus are largely unreliable, since they apply the name to any and all sorts of incendiary substances.^[30]

In attempting to reconstruct the Greek fire system, the concrete evidence, as it emerges from the contemporary literary references, provides the following characteristics:

• It burned on water, and, according to some interpretations, was ignited by water. In addition, as numerous writers testify, it could be extinguished only by a few substances, such as sand (which deprived it of oxygen), strong vinegar, or old urine, presumably by some sort of chemical reaction.^[39][40][41]
• It was a liquid substance, and not some sort of projectile, as verified both by descriptions and the very name "liquid fire".^[39][40]
• At sea, it was usually ejected from a siphōn,^[39][40] although earthenware pots or grenades filled with it or similar substances were also used.^[42]
• The discharge of Greek fire was accompanied by "thunder" and "much smoke".^[39][40][43]

Theories on composition[edit]

The first and, for a long time, most popular theory regarding the composition of Greek fire held that its chief ingredient was saltpeter, making it an early form of gunpowder,^[44][45] this argument was based on the "thunder and smoke" description, as well as on the distance the flame could be projected from the siphōn, which suggested an explosive discharge.^[46] From the times of Isaac Vossius,^[2] several scholars adhered to this position, most notably the so-called "French school" during the 19th century, which included chemist Marcellin Berthelot.^[47][48] This view has been rejected since, as saltpeter does not appear to have been used in warfare in Europe or the Middle East before the 13th century, and is absent from the accounts of the Muslim writers—the foremost chemists of the early medieval world^[49]—before the same period.^[50] In addition, the nature of the proposed mixture would have been radically different from the siphōn-projected substance described by Byzantine sources.^[51]

A second view, based on the fact that Greek fire was inextinguishable by water (some sources suggest that water intensified the flames) suggested that its destructive power was the result of the explosive reaction between water and quicklime, although quicklime was certainly known and used by the Byzantines and the Arabs in warfare,^[52] the theory is refuted by literary and empirical evidence. A quicklime-based substance would have to come in contact with water to ignite, while Emperor Leo's Tactica indicate that Greek fire was often poured directly on the decks of enemy ships,^[53] although admittedly, decks were kept wet due to lack of sealants. Likewise, Leo describes the use of grenades,^[54] which further reinforces the view that contact with water was not necessary for the substance's ignition.^[55] Furthermore, C. Zenghelis pointed out that, based on experiments, the actual result of the water–quicklime reaction would be negligible in the open sea.^[56] Another similar proposition suggested that Kallinikos had in fact discovered calcium phosphide, which can be made by boiling bones in urine within a sealed vessel,^[57] on contact with water, calcium phosphide releases phosphine, which ignites spontaneously. However, extensive experiments with it also failed to reproduce the described intensity of Greek fire.^[58][59]

Although the presence of either quicklime or saltpeter in the mixture cannot be entirely excluded, they were consequently not the primary ingredient.^[59][46] Most modern scholars agree that Greek fire was based on petroleum, either crude or refined; comparable to modern napalm. The Byzantines had easy access to crude oil from the naturally occurring wells around the Black Sea (e.g., the wells around Tmutorakan noted by Constantine Porphyrogennetos) or in various locations throughout the Middle East.^[44][60][61] An alternate name for Greek fire was "Median fire" (μηδικὸν πῦρ),^[2] and the 6th-century historian Procopius, records that crude oil, called "naphtha" (in Greek: νάφθα naphtha, from Old Persian 𐎴𐎳𐎫 naft) by the Persians, was known to the Greeks as "Median oil" (μηδικὸν ἔλαιον).^[62] This seems to corroborate the use of naphtha as a basic ingredient of Greek fire.^[63] Naphtha was also used by the Abbasids in the 9th century, with special troops, the naffāṭūn, who wore thick protective suits and used small copper vessels containing burning oil, which they threw onto the enemy troops.^[64] There is also a surviving 9th century Latin text, preserved at Wolfenbüttel in Germany, which mentions the ingredients of what appears to be Greek fire and the operation of the siphōns used to project it. Although the text contains some inaccuracies, it clearly identifies the main component as naphtha.^[2][65] Resins were probably added as a thickener (the Praecepta Militaria refer to the substance as πῦρ κολλητικόν, "sticky fire"), and to increase the duration and intensity of the flame.^[66][67] A modern theoretical concoction included the use of pine tar and animal fat along with other ingredients.^[68]

A 12th century treatise prepared by Mardi bin Ali al-Tarsusi for Saladin records an Arab version of Greek fire, called naft, which also had a petroleum base, with sulfur and various resins added. Any direct relation with the Byzantine formula is unlikely.^[69] An Italian recipe from the 16th century has been recorded for recreational use; it includes coal from a willow tree, alcohol, incense, sulfur, wool and camphor as well as two undetermined components (burning salt and pegola), the concoction was guaranteed to "burn under water" and to be "beautiful".^[70]

Methods of deployment[edit]

Use of a cheirosiphōn ("hand-siphōn"), a portable flamethrower, used from atop a flying bridge against a castle. Illumination from the Poliorcetica of Hero of Byzantium.

The chief method of deployment of Greek fire, which sets it apart from similar substances, was its projection through a tube (siphōn), for use aboard ships or in sieges. Portable projectors (cheirosiphōnes) were also invented, reputedly by Emperor Leo VI, the Byzantine military manuals also mention that jars (chytrai or tzykalia) filled with Greek fire and caltrops wrapped with tow and soaked in the substance were thrown by catapults, while pivoting cranes (gerania) were employed to pour it upon enemy ships.^[71][72] The cheirosiphōnes especially were prescribed for use at land and in sieges, both against siege machines and against defenders on the walls, by several 10th-century military authors, and their use is depicted in the Poliorcetica of Hero of Byzantium.^[73][74] The Byzantine dromons usually had a siphōn installed on their prow under the forecastle, but additional devices could also on occasion be placed elsewhere on the ship, thus in 941, when the Byzantines were facing the vastly more numerous Rus' fleet, siphōns were placed also amidships and even astern.^[75]

Projectors[edit]

The use of tubular projectors (σίφων, siphōn) is amply attested in the contemporary sources. Anna Komnene gives this account of beast-shaped Greek fire projectors being mounted to the bow of warships:^[76]

As he [the Emperor Alexios I] knew that the Pisans were skilled in sea warfare and dreaded a battle with them, on the prow of each ship he had a head fixed of a lion or other land-animal, made in brass or iron with the mouth open and then gilded over, so that their mere aspect was terrifying. And the fire which was to be directed against the enemy through tubes he made to pass through the mouths of the beasts, so that it seemed as if the lions and the other similar monsters were vomiting the fire.

Some sources provide more information on the composition and function of the whole mechanism, the Wolfenbüttel manuscript in particular provides the following description:^[65]

...having built a furnace right at the front of the ship, they set on it a copper vessel full of these things, having put fire underneath. And one of them, having made a bronze tube similar to that which the rustics call a squitiatoria, "squirt", with which boys play, they spray [it] at the enemy.

Another, possibly first-hand, account of the use of Greek fire comes from the 11th-century Yngvars saga víðförla, in which the Viking Ingvar the Far-Travelled faces ships equipped with Greek fire weapons:^[77]

[They] began blowing with smiths’ bellows at a furnace in which there was fire and there came from it a great din. There stood there also a brass [or bronze] tube and from it flew much fire against one ship, and it burned up in a short time so that all of it became white ashes...

The account, albeit embellished, corresponds with many of the characteristics of Greek fire known from other sources, such as a loud roar that accompanied its discharge,^[78] these two texts are also the only two sources that explicitly mention that the substance was heated over a furnace before being discharged; although the validity of this information is open to question, modern reconstructions have relied upon them.^[79][80]

Proposed reconstruction of the Greek fire mechanism by Haldon and Byrne

Based on these descriptions and the Byzantine sources, John Haldon and Maurice Byrne designed a hypothetical apparatus as consisting of three main components: a bronze pump, which was used to pressurize the oil; a brazier, used to heat the oil (πρόπυρον, propyron, "pre-heater"); and the nozzle, which was covered in bronze and mounted on a swivel (στρεπτόν, strepton).^[81] The brazier, burning a match of linen or flax that produced intense heat and the characteristic thick smoke, was used to heat oil and the other ingredients in an airtight tank above it,^[82] a process that also helped to dissolve the resins into a fluid mixture,^[66] the substance was pressurized by the heat and the usage of a force pump. After it had reached the proper pressure, a valve connecting the tank with the swivel was opened and the mixture was discharged from its end, being ignited at its mouth by some source of flame,^[83] the intense heat of the flame made necessary the presence of heat shields made of iron (βουκόλια, boukolia), which are attested in the fleet inventories.^[84]

The process of operating Haldon and Byrne's design was fraught with danger, as the mounting pressure could easily make the heated oil tank explode, a flaw which was not recorded as a problem with the historical fire weapon;^[85][86] in the experiments conducted by Haldon in 2002 for the episode "Fireship" of the television series Machines Times Forgot, even modern welding techniques failed to secure adequate insulation of the bronze tank under pressure. This led to the relocation of the pressure pump between the tank and the nozzle, the full-scale device built on this basis established the effectiveness of the mechanism's design, even with the simple materials and techniques available to the Byzantines. The experiment used crude oil mixed with wood resins, and achieved a flame temperature of over 1,000 °C (1,830 °F) and an effective range of up to 15 meters (49 ft).^[87]

Hand-held projectors[edit]

Detail of a cheirosiphōn

The portable cheirosiphōn ("hand-siphōn"), the earliest analogue to a modern flamethrower, is extensively attested in the military documents of the 10th century, and recommended for use in both sea and land. They first appear in the Tactica of emperor Leo VI the Wise, who claims to have invented them.^[41] Subsequent authors continued to refer to the cheirosiphōnes, especially for use against siege towers, although Nikephoros II Phokas also advises their use in field armies, with the aim of disrupting the enemy formation.^[73] Although both Leo VI and Nikephoros Phokas claim that the substance used in the cheirosiphōnes was the same as in the static devices used on ships, Haldon and Byrne consider that the former were manifestly different from their larger cousins, and theorize that the device was fundamentally different, "a simple syringe [that] squirted both liquid fire (presumably unignited) and noxious juices to repel enemy troops." The illustrations of Hero's Poliorcetica show the cheirosiphōn also throwing the ignited substance, ^[88][89] but such illustrations were narrative in intent, so that showing the device throwing the ignited substance may have seemed preferable to trying to clearly illustrate throwing the unignited substance and then igniting it.

Grenades[edit]

In its earliest form, Greek fire was hurled onto enemy forces by firing a burning cloth-wrapped ball, perhaps containing a flask, using a form of light catapult, most probably a seaborne variant of the Roman light catapult or onager, these were capable of hurling light loads—around 6 to 9 kg (13 to 20 lb)—a distance of 350–450 m (380–490 yd).

Effectiveness and countermeasures[edit]

Although the destructiveness of Greek fire is indisputable, it did not make the Byzantine navy invincible, it was not, in the words of naval historian John Pryor, a "ship-killer" comparable to the naval ram, which, by then, had fallen out of use.^[90] While Greek fire remained a potent weapon, its limitations were significant when compared to more traditional forms of artillery: in its siphōn-deployed version, it had a limited range, and it could be used safely only in a calm sea and with favourable wind conditions.^[91]

The Muslim navies eventually adapted themselves to it by staying out of its effective range and devising methods of protection such as felt or hides soaked in vinegar.^[41]

In popular culture[edit]

Film[edit]

• Greek fire made an appearance in the film Pirates of the Caribbean: On Stranger Tides (2011) as a naval weapon used by the character Blackbeard.
• Greek fire also appeared in the movie Timeline (2003) where an archaeologist from the modern day gives the English the secrets of Greek Fire for his life. In the film, water applied in an effort to extinguish it spread the fire instead.
• Greek fire was used in the film Sinbad the Sailor (1947, Technicolor) by Sinbad (Douglas Fairbanks, Jr.) to vanquish the Emir of Daibul (Anthony Quinn) in a rowboat while saving Shireen (Maureen O'Hara) and the lost treasure of Alexander the Great (the movie referred to it as the "eighth" voyage of Sinbad).
• Greek fire was used in naval battles in the 2014 movie 300: Rise of an Empire.

Games[edit]

• Greek fire has appeared in multiple video games, including Defender of the Crown, Assassin's Creed: Revelations, Total War: Attila, Age of Empires, Age of Empires II, and Medieval II: Total War: Kingdoms. Greek fire also makes an appearance in the game Rise of the Tomb Raider, wherein the formula is found in the modern day in an excavation and used to increase the potency of fire-related armaments, because of which, it was given the name "Holy Fire" in the game, it makes an additional appearance in Crusader Kings II in an event chain that entails the theft (and potential recovery) of its formula.

Literature[edit]

• Both the academic discussion of Greek fire and a medieval demonstration of it appear in Michael Crichton's novel Timeline (1999) and its 2003 film adaptation.
• A similar substance, known as "wildfire", is used in a naval battle in George R. R. Martin's book A Clash of Kings. This green substance is deployed in fragile clay jars, never from tubes, and is apparently partly magical in nature, but, like Greek fire, it burns on water.
• Greek fire is a common weapon used in Rick Riordan's Percy Jackson & the Olympians series as well as its spin-off series, The Heroes of Olympus. However, the literature's version of the weapon is green.
• Greek fire also plays a part in saving the city of Boston from destruction in Matthew Pearl's novel, The Technologists (2012).^[92]
• In the "Notes from the Historical Record" section of his tenth Sigma Force novel (page 1 of 2) The Sixth Extinction, James Rollins calls Greek fire's modern day equivalent napalm.
• In C. J. Sansom's historical mystery novel Dark Fire, Thomas Cromwell sends the lawyer Matthew Shardlake to recover the secret of Greek fire, following its discovery in the library of a dissolved London monastery.^[93]
• In Chapter 96, "The Try-Works", of Herman Melville's Moby-Dick, the nighttime light effects aboard the whale ship Pequod whilst engaged in rendering blubber at sea are likened to "the famed Greek fire".
• In Rachel Caine's The Great Library series, Greek fire is a liquid weapon used by Burners, the Welsh army, the High Garda, and the Great Library itself. It is described as green in appearance and the smoke is also mentioned as being toxic to breathe.
• In Raymond E. Feist's fiction Riftwar Chronicles, the island nation of Queg (somewhat based on the real-world Greece) produces a substance known as "(Quegan) Fire Oil" which can burn on water and can only be doused with sand. The Fire Oil is created from naptha mixed with some other ingredients.
• In David Gemmell's Troy series, Helikaon's ship the Xanthos is equipped with "fire hurlers" that throw large wax-sealed clay pots filled with "nephthar" which would burst on the deck of an enemy vessel and be ignited by fire arrows. Contact with water caused the flames to spread and rage higher and hotter, the books describe sailors aflame with "nephthar" jumping overboard and continuing to burn as they sink into the depths.

Music[edit]

• In their album Turisas2013, the Finnish heavy metal band Turisas recorded a track entitled "Greek Fire", referencing its secret recipe and ability to burn on water in lyrics such as: "A secret compound,/No one knows,/How to put out the blaze?/When water you throw,/Feeds the flames".^[94]

Television[edit]

• A similar substance called "wildfire" appears in the HBO series Game of Thrones. In Season 2 Episode 9 wildfire used in defending King's Landing destroyed half a fleet of attacking ships; in Season 6 Episode 10, wildfire is used to blow up the Great Sept, killing many important characters.
• A self-igniting liquid, referred to as "Greek fire" in Season 1 Episodes 7–11 of the BBC America television series Copper, is featured as part of a plot by Confederate Secret Service agents to burn down New York City in 1864.
• Greek fire was used in the episode "The Mask of Doom, Part III" of the Fantastic Four 1994 TV series to thwart the Persians and Dr. Doom.
• Called "Byzantine fire", it was used in the last episode of the 2006 TV series Robin Hood.
• Mentioned in the same Robin Hood TV series, in the earlier episode "A Thing or Two About Loyalty", as Greek fire and black powder, but it was argued by the Saracen character, Djaq, that it was actually a Saracen invention.
• In an episode of the Sleepy Hollow TV series, "Dead Men Tell No Tales", Ichabod Crane described the Greek Fire as a fire that could not be extinguished by water or sand, and would only go out after there was nothing left to burn. He stated that it was what was caused the Great Fire of New York, that burned Manhattan during the American Revolutionary War. Weapons that generate Greek fire are discovered in George Washington's tomb when Ichabod Crane and Abbie Mills find their way there with aid from Agent Seeley Booth and Doctor Temperance "Bones" Brennan. A later episode, "Blood from a Stone", had canisters of Greek fire.
