He also used writings of Gregory Thaumaturgus, Archelaus, Acacius,Didymus, George of Laodicea, Gregory Nazianzen, Timothy of Berytus (see Lietzmann, A pollinaris von Laodicea, p. 44), Nestorius, Eusebius Scholasticus, Philip of Side, Evagrius, Palladius, Eutropius, the emperor Julian and orations of Libanius and Themistius; and he was apparently acquainted with some of the works of Origen and with Pamphilus' Apologia pro Origene.
The principal works of Gregory Thaumaturgus are the Panegyricus in Origenem (Eis 't ptybniv iravrnvpucos Xbyos), which he wrote when on the point of leaving the school of that great master (it contains a valuable minute description of Origen's mode of instruction), a Metaphrasis in Ecclesiasten, characterized by Jerome as " short but useful "; and an Epistola canonica, which treats of the discipline to be undergone by those Christians who under pressure of persecution had relapsed into paganism, but desired to be restored to the privileges of the Church.
There was in the whole family a tendency to ecstatic emotion and enthusiastic piety, and it is worth noting that Cappadocia had already given to the Church men like Firmilian and Gregory Thaumaturgus.
