Basically this
bust is laureate,
cuirassed r., seen from front, with fold of cloak on front shoulder.
Not "draped", which is a sloppy expression in English, also occurring in
French and
German (drapé/drapiert), for "wearing cloak (Latin
paludamentum) around shoulders". Joe's
bust type shows only a fold of the
paludamentum on front shoulder, not
paludamentum covering chest and back, which would make it "draped" in the conventional classification.
This coin might also have the
thunderbolt on
cuirass strap, which
Eric pointed out as occurring on some Hadrianic
sestertii, plus a winged frontal
Medusa head (
gorgoneion) on the breast of Hadrian's
cuirass. In Eric's earlier
thread I
had only checked Hadrian's
sestertii for that
thunderbolt on
cuirass strap, but the same motif seems also to occur on
aurei and
denarii, not so clear on Joe's
denarius but confirmed by the
denarius from
CoinArchives reproduced below. The apparent
gorgoneion, however, could also use confirmation from a clearer example.
