The portraits of Sabina represent a shift in the representation of imperial women in the Roman Empire. Sabina is the first empress to appear as the obverse portrait of a continuous coin production at Rome and the first woman to appear on all of the main denominations at the central mint. Her portraiture is also more varied than that of any previous empress. She is represented on imperial coinage with five different portrait types—i.e., modes of representation—most easily distinguished by hairstyle, all of which are depicted below. This is matched by an increased presence of Sabina’s portraits in provincial coinage and sculpture.
