The island was now reduced to a Roman province, and subsequently united for administrative purposes with the district of Cyrenaica or the Pentapolis, on the opposite coast of Africa.
Ptolemy Apion meanwhile, dying in 96, had bequeathed the Cyrenaica to Rome.
About the Cyrenaica we are still insufficiently informed.
Cyrenaica, on the east, attached to Egypt, was then excluded from it, and, similarly, Mauretania, on the west.
The military posts were drawn up in echelon along the frontier of the desert, especially along the southern slopes of the Aures, as far as Ad Majores (Besseriani), and on the Tripolitan frontier as far as Cydamus (Ghadames), forming an immense arc extending from Cyrenaica to Mauretania.
