Lucius Tarquinius Superbus was the legendary seventh and final king of Rome, reigning from 535 BC until the popular uprising in 509 BC that led to the establishment of the Roman Republic. He is known as Tarquin the Proud, from his cognomen Superbus. Ancient accounts of the regal period mingle legend. Tarquin was said to have been the son or grandson of Lucius Tarquinius Priscus, the fifth king of Rome, to have gained the throne through the murders of both his wife and his elder brother, followed by the assassination of his predecessor, Servius Tullius, his reign is described as a tyranny. Tarquin was said to be the son or grandson of Lucius Tarquinius Priscus, the fifth king of Rome, Tanaquil. Tanaquil had engineered her husband's succession to the Roman kingdom on the death of Ancus Marcius; when the sons of Marcius subsequently arranged the elder Tarquin's assassination in 579 BC, Tanaquil placed Servius Tullius on the throne, in preference to her own sons. According to an Etruscan tradition, the hero Macstarna equated with Servius Tullius and killed a Roman named Gnaeus Tarquinius, rescued the brothers Caelius and Aulus Vibenna from captivity.
This may recollect an otherwise forgotten attempt by the sons of Tarquin the Elder to reclaim the throne. To forestall further dynastic strife, Servius married his daughters, known to history as Tullia Major and Tullia Minor, to Lucius Tarquinius Superbus, the future king, his brother Arruns. One of Tarquin's sisters, married Marcus Junius Brutus, was the mother of Lucius Junius Brutus, one of the men who would lead the overthrow of the Roman Kingdom; the elder sister, Tullia Major, was of mild disposition, yet married the ambitious Tarquin. Her younger sister, Tullia Minor, was of fiercer temperament, she came to despise him, conspired with Tarquin to bring about the deaths of Tullia Major and Arruns. After the murder of their spouses and Tullia were married. Together, they had three sons: Titus and Sextus, a daughter, who married Octavius Mamilius, the prince of Tusculum. Tullia encouraged her husband to advance his own position persuading him to usurp Servius. Tarquin solicited the support of the patrician senators those from families who had received their senatorial rank under Tarquin the Elder.
He bestowed presents upon them, spread criticism of Servius the king. In time, Tarquin felt ready to seize the throne, he went to the senate-house with a group of armed men, sat himself on the throne, summoned the senators to attend upon King Tarquin. He spoke to the senators, denigrating Servius as a slave born of a slave; when word of this brazen deed reached Servius, he hurried to the curia to confront Tarquin, who leveled the same accusations against his father-in-law, in his youth and vigor carried the king outside and flung him down the steps of the senate-house and into the street. The king's retainers fled, as he made his way and unattended, toward the palace, the aged Servius was set upon and murdered by Tarquin's assassins on the advice of his own daughter. Tullia, drove in her chariot to the senate-house, where she was the first to hail her husband as king, but Tarquin bade her return home, concerned. As she drove toward the Urbian Hill, her driver stopped horrified at the sight of the king's body, lying in the street.
But in a frenzy, Tullia herself seized the reins, drove the wheels of her chariot over her father's corpse. The king's blood spattered against the chariot and stained Tullia's clothes, so that she brought a gruesome relic of the murder back to her house; the street where Tullia disgraced the dead king afterward became known as the Vicus Sceleratus, the Street of Crime. Tarquin commenced his reign by refusing to bury the dead Servius, putting to death a number of leading senators, whom he suspected of remaining loyal to Servius. By not replacing the slain senators, not consulting the senate on matters of government, he diminished both the size and the authority of the senate. In another break with tradition, Tarquin judged capital crimes without the advice of counselors, causing fear amongst those who might think to oppose him, he made a powerful ally when he betrothed his daughter to Octavius Mamilius of Tusculum, among the most eminent of the Latin chiefs. Early in his reign, Tarquin called a meeting of the Latin leaders to discuss the bonds between Rome and the Latin towns.
The meeting was held at a grove sacred to the goddess Ferentina. At the meeting, Turnus Herdonius inveighed against Tarquin's arrogance, warned his countrymen against trusting the Roman king. Tarquin bribed Turnus' servant to store a large number of swords in his master's lodging. Tarquin called together the Latin leaders, accused Turnus of plotting his assassination; the Latin leaders accompanied Tarquin to Turnus' lodging and, the swords being discovered, the Latin's guilt was speedily inferred. Turnus was condemned to be thrown into a pool of water in the grove, with a wooden frame, or cratis, placed over his head, into which stones were thrown, drowning him; the meeting of the Latin chiefs conti
Histogenesis is the formation of different tissues from undifferentiated cells. These cells are constituents of three primary germ layers, the endoderm and ectoderm; the science of the microscopic structures of the tissues formed within histogenesis is termed histology. A germ layer is a collection of cells, formed during animal and mammalian embryogenesis. Germ layers are pronounced within vertebrate organisms. Animals with radial symmetry, such as cnidarians, produce two layers, called the ectoderm and endoderm. Therefore, they are diploblastic. Animals with bilateral symmetry produce a third layer in-between called mesoderm, making them triploblastic. Germ layers will give rise to all of an animal’s or mammal's tissues and organs through a process called organogenesis; the endoderm is one of the germ to penes layers formed during animal embryogenesis. Cells migrating inward along the archenteron form the inner layer of the gastrula, which develops into the endoderm; the endoderm consists of flattened cells, which subsequently become columnar.
The mesoderm germ layer forms in the embryos of animals and mammals more complex than cnidarians, making them triploblastic. During gastrulation, some of the cells migrating inward to form the endoderm form an additional layer between the endoderm and the ectoderm. A theory suggests that this key innovation evolved hundreds of millions of years ago and led to the evolution of nearly all large, complex animals; the formation of a mesoderm led to the formation of a coelom. Organs formed inside a coelom can move and develop independently of the body wall while fluid cushions and protects them from shocks; the ectoderm is the start of a tissue. It forms from the outermost of the germ layers; the proceeding graph represents the products produced by the three germ layers.
