College of Aesculapius and Hygia
The College of Aesculapius and Hygia was an association (collegium) founded in the mid-2nd century AD by a wealthy Roman woman named Salvia Marcellina, in honor of her dead husband and the procurator for whom he had worked. It is known from a lengthy inscription, dated March 11, 153 AD, that preserves the statute (lex) under which the college was constituted.
