Phaenias of Eresus, 4th century BCE, of Eresus on Lesbos, heard Aristotle, a contemporary of Theophrastus.
None of his books survive intact. Later writers name The Tyrants of Sicily, On the Socratics, On the Poets, and On Plants.
What this site holds is fragments in later hosts. A passage here is a later mouth, not Aristotle’s autograph.
