[Sidenote:12] Longinus was the commandant of the Roman camp who had made himself a terror to the Dacian leader in warfare.
Longinus was not a priest, but a deacon, and travelled here and there in that capacity, preaching the name of Christ, and giving, as an eye-witness, a history of his Passion and Resurrection.
It appears from this passage of Syrianus that Longinus was the original inventor of the theory of abstract ideas; and that Mr. Locke was merely the restorer of it.
