Horapollo
, or Horus Apollo, was a grammarian, according to Suidas, of Panoplus in Egypt, who taught first at Alexandria, and then at Constantinople, under the reign of Theodosius, about the year 380. There are extant under his name two books “concerning the Hieroglyphics of the Egyptians,” which Aldus first published in Greek in 1505, folio. They have often been republished since, with a Latin version and notes; but the best edition is that by Cornelius de Pauw at Utrecht, in 1727, 4to. Meanwhile there are many Rorapollos of antiquity; and it is not certain, that the grammarian of Alexandria was the author of these books. Suidas does not ascribe them to him; and Fabricius is of opinion, that they belong rather to another Horus Apollo of more ancient | standing, who flourished about 1500 B. C. and wrote upon Hieroglyphics in the Egyptian language, and from whose work an extract rather than a version has been made of these two books in Greek. 1
