Alcimus (Greek, Ancient (to 1453);: Ἄλκιμος) was a Greek rhetorician who flourished around 300 BC.[1] He was called by Diogenes Laërtius the most distinguished of all Greek rhetoricians.[2] It is not certain whether he is the same as the Alcimus to whom Diogenes in another passage ascribes a work called Pros Amuntan (Greek, Ancient (to 1453);: πρὸς Ἀμύνταν).[3] Athenaeus in several places speaks of a Sicilian Alcimus, who appears to have been the author of a great historical work, parts of which are referred to under the names of Italica (Greek, Ancient (to 1453);: Ἰταλικὰ) and Sicelica (Greek, Ancient (to 1453);: Σικελικά). But whether he was the same as the rhetorician Alcimus, cannot be determined.[4]
