Acron
Acron (), son of Xenon, was a Greek physician born at Agrigentum (Gk. Acragas). Life. The exact dates of Acron is not known; but, as he is mentioned as being contemporary with Empedocles, who died about the beginning of the Peloponnesian War, he must have lived in the fifth century BC. From Sicily he went to Athens and there opened a philosophical school (). It is said that Acron was in that city during the great plague (430 BC) and that large fires kindled in the streets at his direction for the purpose of purifying the air proved of great service  to several of the sick. There is, however, no mention of this in Thucydides, and if Empedocles or Simonides (d. 467 BC) in fact wrote the epitaph on Acron, he may not have been in Athens during the plague. On Acron's return to his native country, the physician asked the senate for a spot of ground where he might build a family tomb. The request was refused at the suggestion of Empedocles, who conceived that such a grant for such a purpose would interfere with the principle of equality that he was anxious to establish at Agrigentum. Because the  ironic epitaph on the "Acragantine Acron" is among the most replete "jeux de mot" on record, it so challenges translation that it will be given in Greek to preserve the paronomasia of the original: The second line was sometimes read thus: More or less: "The lofty physician Loftyman of Loftyville, son of a lofty father, is hidden here under a lofty crag in the loftiest of fatherlands," or "is covered by the lofty tomb of a very lofty peak." Some attributed the whole epigram to Simonides. Pliny considers Acron as the first of the "Empirics". But this has been considered  an error, for the sect alluded to did not arise until the third century BC, roughly 200 years after the time of Acron. Some scholars consider that the sect of the Empirici, in order to boast of a greater antiquity than the Dogmatics (founded about 400 BC by Thessalus the son and Polybus the son-in-law of Hippocrates), merely claimed Acron as their founder. None of Acron's works are now extant, though he wrote several in the Doric dialect on medical and physical subjects, the titles of which are preserved by the Suda and Eudocia.
