Of the cities of Sicily bearing the name "Hybla", it is much the least known from ancient sources. No allusion to it is found in Pausanias, where he is distinguishing Hybla Major from Hybla Minor, nor in any of the geographers: but we find in the Itineraries a town of Hybla, placed on the line of road from Syracuse to Agrigentum (modern Agrigento, which is certainly distinct from both Hybla Major and Minor (and from Megara Hyblaea and Hybla Gereatis which may equate with them), and can therefore be no other than the third Hybla of Stephanus.
