I know of only two potbanks that made Aesculapius. His female counterpart, on the other hand, seems to have been a far more popular subject.
So aren't classical figures fascinating? If you want Aesculapius, you will have to be patient. Hygiea is easy to find, particularly if you tolerate a mediocre example. But a beauty, like the one shown here, requires a little more patience and is well worth the wait.
