ALBA JULIA (anc. geog.), now Weissenburg, a town of Transylvania, on the river Marisus, or Merisch, to the west of Hermanstat, supposed to be called Alba Julia, after Julia Domna the mother of Caracalla. There are, however, several inscriptions found at or near Weissenburg, which bear COL. APUL. that is Colonia Apulensis, without the least mention of Alba Julia, though inscribed after Caracalla's time. Add, that Ulpian, reciting the colonies of Dacia, calls this colony Apulensis, and neither Alba nor Julia. Whence there is a suspicion, that Alba Julia is a corruption of Apulum. It was also called Apulum Augustum. E. Long. 25. 0. Lat. 46. 46.
