ALIMENTARIUM PUERI, &c. were certain children maintained and educated by the munificence of the emperors, in a sort of public places not unlike our hospitals. Trajan was the first who brought up any of these alimentary boys. He was imitated by Adrian. Antoninus Pius did the same for a number of maids, at the solicitation of Faustina; and hence, in some medals of that empress, we read PVELLAE FAUSTINIANAE.—Alexander Severus did the like at the request of Mammæa; and the maids thus educated were called Mammæanæ.
