Lesches in Harpers Dictionary of Classical Antiquities
（Λέσχης) or Lescheus (Λέσχευς). A Cyclic poet, a native of Mitylené or Pyrrha, in the island of Lesbos, and considerably later than Arctinus. The best authorities concur in placing him in the time of Archilochus, or about B.C. 708-676. Hence the account which we find in ancient authors, of a contest between Arctinus and Lesches, can only mean that the latter competed with the earlier poet in treating the same subjects. His poem, in four books, which was attributed by many to Homer, and, besides, to very different authors, was called the "Little Iliad" (Ἰλιὰς Μικρά), and was clearly intended as a supplement to the great Iliad. It is learned from Aristotle (Poet. 23) that it comprised the events before the fall of Troy, the fate of Aiax, the exploits of Philoctetes, Neoptolemus, and Odysseus, which led to the taking of the city, as well as the account of the destruction of Troy itself; which statement is confirmed by numerous fragments. The last part of this (like the first part of the poem of Arctinus) was called the "Destruction of Troy" (Ἰλίου Πέρσις), from which Pausanias makes several quotations with reference to the sacking of Troy and the partition and carrying away of the prisoners. See Cyclici Poetae; Homerus.
Lesches in Wikipedia
Lesches is a semi-legendary early Greek poet and the reputed author of the Little Iliad. According to the usually accepted tradition, he was a native of Pyrrha in Lesbos, and flourished about 660 BC (others place him about 50 years earlier). He may have spent part of his career at Mytilene, for Proclus refers to him as "Lesches of Mytilene".
The lost epic Little Iliad, in four books, took up the story of the Homeric Iliad, and, beginning with the contest between Telamonian Ajax and Odysseus for the arms of Achilles, carried it down to the feast of the Trojans over the captured Trojan Horse, according to the epitome in Proclus, or to the Fall of Troy, according to Aristotle. Some ancient authorities ascribe the work to a Spartan named Cinaethon, and even to Homer.
