[1] The headword is masculine nominative singular, aorist middle participle, of LSJ's a)ma/w (A) (cf. alpha 1579, and more generally alpha 1574, and delta 654). Perhaps, though not demonstrably, extracted from the first quotation given. (Ostensibly, the headword occurs also in Homer, Odyssey 9.247, but there it is from the LSJ's a)ma/w (B); cf. Hesychius alpha3640.)
[2] Quotation (transmitted, in Adler's view, via the Excerpta Constantini Porphyrogeniti) unidentifiable. (Adler suggested Aelian, on no discernible basis.)
[3] Greek Anthology 7.241.3-4 (Antipater of Sidon); an elegy on a young Ptolemaic prince who perished in an epidemic; cf. Gow and Page (vol. I, 20) and (vol. II, 54-5). See further extracts from this epigram at delta 102, delta 1316, epsilon 9, theta 525, tau 454, and tau 573. The prince's identity remains uncertain, but Gow and Page (vol. II, 54) find Laqueur's (148) arguments for Eupator, son of Ptolemy Philometor (reigned 180-ca.145 BCE) and Chichorius, to be very strong.
