What is "antileon"

Antileon was an ancient Greek author who wrote a work on chronology , the second book of which is referred to by Diogenes Laërtius. Whether he is the same person as the Antileon mentioned by Julius Pollux is uncertain.

"Antileon" in Greek mythology is also the name of one of the twin sons of Heracles and Procris, and brother to Hippeus (or Hipparinus).
