a town of Istria, mentioned only by Pliny 3.19. s. 23
), which appears to have been in his time a place of little importance; but from an inscription cited by Cluverius (Ital.
p. 210) it appears that it was restored by the emperor Justin II. who bestowed on it the name of JUSTINOPOLIS. This inscription is preserved at Capo d'Istria,
now a considerable town, situated on a small island joined to the mainland by a causeway, which appears to have been termed AEGIDIS INSULA, and was probably the site of the Aegida of Pliny.
