Ἑρμαθήνη
From LSJ
English (LSJ)
ἡ,
A terminal bust (cf. Ἑρμῆς 1.2) with head of Athena, Cic.Att.1.1.5, 1.4.3; so of busts with heads of other divinities, of Eros, Ἑρμ-έρως, Plin.HN36.33 (pl.); of Heracles, Ἑρμ-ηρακλῆς, Cic.Att.1.10.3, Milet.1(7) No.305; of Pan, cf. Ἑρμόπαν. (Cic.Att.1.4.3 appears to explain Hermathena as a Janus-like bust of Hermes and Athena; this is perh. a pun, but cf. Ἑρμῆς 1.2.)
