addressed to the Roman Senate a severe lecture and called them to repentance. His sons, Honorius in the West and Arcadius in the East, followed the example of their father. Under the successor of the latter, =Theodosius II.= (A.D. 408-450), monks with imperial authority for the suppression of heathenism traversed the provinces, and in A.D. 448, in common with =Valentinian III.= (A.D. 425-455), the western emperor, he issued an edict which strictly enjoined the burning of all pagan polemical writings against Christianity, especially those of Porphyry “the crack-brained,” wherever they might be found. This period is also marked by deeds of bloody violence. The most horrible of these was the murder of the noble pagan philosopher Hypatia, the learned daughter of Theon the mathematician, at Alexandria in A.D. 415. Officially paganism may be regarded as no longer existent. Branded long even before this as the religion of the peasants (such is the derivation of the word paganism), it was now almost wholly confined to remote rural districts. Its latest and solitary stronghold was the University of Athens raised to the summit of its fame under Proclus (§ 24, 2). =Justinian I.= (A.D. 527-565) decreed the suppression of this school in A.D. 529. Its teachers fled into Persia, and there laid the first foundations of the later literary period of Islam under the ruling family of the Abassidæ at Bagdad (§ 65, 2). This was the death hour of heathenism in the Roman empire. The Mainottæ in the mountains of the Peloponnesus still maintained their political independence and the heathen religion of their fathers down to the 9th century. In the Italian islands, too, of Sardinia, Corsica, and Sicily, there were still many heathens even in the time of Gregory the Great († 604).[116]
