Croesus was the king of Lydia, who reigned from 585 BC until his defeat by the Persian king Cyrus the Great in 547 or 546 BC. According to Herodotus, he reigned 14 years. Croesus was renowned for his wealth; Herodotus and Pausanias noted that his gifts were preserved at Delphi. The fall of Croesus had a profound effect on the Greeks, providing a fixed point in their calendar. "By the fifth century at least", J. A. S. Evans has remarked, "Croesus had become a figure of myth, who stood outside the conventional restraints of chronology."

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.
