or HORUS APOLLO, a grammarian of Panoplis in Egypt, according to Suidas, who first taught at Alexandria, and then at Constantinople under the reign of Theodosius. There are extant, under his name, two books on the hieroglyphics of the Egyptians; which Aldus first published in Greek in 1503, in folio; and they have often been published since, with a Latin version and notes. It is not certain, however, that the grammarian of Alexandria was the author of these books; they being rather thought to belong to another Horapollo of more ancient date: on which head, see Fabricius's Bibliotheca Graeca.
