Perry Index Perry Index The Perry Index is a widely used index of "Aesop's Fables" or "Aesopica", the fables credited to Aesop, the storyteller who lived in ancient Greece between 620 and 560 BC. Modern scholarship takes the view that Aesop probably did not compose all of the fables attributed to him; indeed, a few are known to have first been used before Aesop lived, while the first record we have of many others is from well over a millennium after his time. Traditionally, Aesop's fables were arranged alphabetically, which is not helpful to the reader. B. E. Perry listed them by
Ancient Greek phonology at the end of a phrase. This usage was standardized in the Byzantine era, and is used in modern editions of Ancient Greek texts. Here it might mark a lowered version of a high-pitched syllable. Greek underwent many sound changes. Some occurred between Proto-Indo-European (PIE) and Proto-Greek (PGr), some between the Mycenaean Greek and Ancient Greek periods, which are separated by about 300 years (the Greek Dark Ages), and some during the Koine Greek period. Some sound changes occurred only in particular Ancient Greek dialects, not in others, and certain dialects, such as Boeotian and Laconian, underwent sound changes similar
