The Cyclic Poets is a shorthand term for the early Greek epic poets, who were approximate contemporaries of Homer.
In the classical period, surviving early epic poems were ascribed to those authors, just as the Iliad and Odyssey were ascribed to Homer.
Most modern scholars place Homer in the 8th century BC.
The other poets listed below seemed to have lived in the 7th to the 5th centuries BC.
Excluding Homer's, none of the works of the cyclic poets has survived.
