Sardis or Sardes was an ancient city best known as the capital of the Lydian Empire. After the fall of the Lydian Empire, it became the capital of the Persian satrapy of Lydia and later a major center of Hellenistic and Byzantine culture. Now an active archaeological site, it is located in modern day Turkey, in Manisa Province near the town of Sart.

Lydian is an extinct Indo-European Anatolian language spoken in the region of Lydia, in western Anatolia. The language is attested in graffiti and in coin legends from the late 8th century or the early 7th century to the 3rd century BCE, but well-preserved inscriptions of significant length are so far limited to the 5th century and the 4th century BCE, during the period of Persian domination. Thus, Lydian texts are effectively contemporaneous with those in Lycian.
