Diogenes Laertius c. 180 – c. 240

Diogenes Laertius (c. 180 – c. 240) was a Greek philosopher of the Ancient era, associated with Hellenistic.

Diogenes Laertius was a Greek biographer of philosophers of the third century AD, the author of the Lives and Opinions of Eminent Philosophers, the most extensive surviving ancient compilation of philosophical biography and doxography. The ten books treat in succession the schools of Greek philosophy from the seven sages and Thales through Plato, Aristotle, the Cynics, the Stoics, the Skeptics, and the Epicureans, ending with a substantial extract of Epicurus's letters. Although his judgments are often eccentric and his quotations not always accurate, his work is, for many of the philosophers he treats, the only source we have, and has shaped the historiography of ancient philosophy for nearly two millennia.
