Who is a Greek fabulist and story teller credited with a number of fables now collectively known as "Aesop's Fables" that has a widely used index of  the storyteller who lived in ancient Greece between 620 and 560 BC?
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 language (Greek then Latin), chronologically, by source, and then alphabetically; the Spanish scholar Francisco Rodríguez Adrados created a similar system. This system also does not help the casual reader, but is the best for scholarly purposes.
Tryphiodorus Tryphiodorus (Greek: Τρυφιόδωρος "Tryphiodoros") is an incorrect spelling for Triphiodorus (Greek: Τριφιόδωρος "Triphiodoros"). The name means ‘gift of Triphis’ (one of the local deities of his home town Panopolis, today Akhmim, in Egypt). The confusion between the two spellings occurred already in the sixth century AD due to iotacism. He is thought to have lived in the third century AD and his only surviving work is "The Sack of Troy", an epic poem in 691 verses. Other recorded titles include "Marathoniaca" and "The Story of Hippodamea".
