Very interesting. On the
gem from
Caesarea the feminine
bust is on a crescent, this means the masculine
bust must be radiated : an imperial couple, no doubt. The emperor looks bearded, and the empress' hairdress looks like
Faustina junior's.
On the lead seal, it seems to me that the emperor's hair looks more like
Constantine and
his sons'. He does not seem laureate, but rather diademed. I am not sure it is an empress facing him, it could be a young
Caesar, w/o diadem. Early 4th C? Could the
legend be the name of the owner of the seal, rather than an imperial name? I know very little about
Roman sigillography...
