The father of Constantine, surnamed “the Great,” who was founder of Constantinople. Constantius governed, as colleague of Diocletian, beyond the Alps, and his dominion extended over Gaul, Britain, and Spain. He died in England whilst preparing for an expedition against the Scots. He was the best of the later Roman Emperors, having a regard to the welfare of his people, and exhibiting no rapacity in his administration. In religious matters he was mild and tolerant, showing great humanity towards the Christians. He had excellent talents, and was surnamed “Chlorus,” or “the pale,” from the pallor of his countenance. [From the marble in the Capitoline Museum at Rome.] 74. HOSTILIANUS. _Roman Emperor_, A.D. 251 or 252. [Date and place of birth unknown. Died A.D. 251 or 252.] Generally regarded as the second son of the Emperor Decius, whom he survived. Declared Cæsar in A.D. 249, and was afterwards adopted by Trebonianus Gallus as his colleague in the empire. Died either of poison or the plague. [From the marble in the Capitoline Museum at Rome.] 75. VOLUSIANUS--CAIUS VIBIUS. _Roman Emperor_, A.D. 252-254. [Date and place of birth unknown. Died at Interamna, in Italy, A.D. 253 or 254.] Son of the Emperor Gallus, with whom he reigned, being elected Augustus in A.D. 252. Little is known of his life or character. When Æmilianus was chosen Emperor, he went with Gallus to oppose him; but, before a battle could be fought, father and son were slain by their own troops. [From the marble in the Capitoline Museum at Rome.] 76*. MAGNUS DECENTIUS. _Roman Prince._ [Date and place of birth unknown. Died at Sens, in Gaul, A.D. 353.] A brother or cousin of the Emperor Flavius Magnentius. Nominated Cæsar, A.D. 351, he went into Gaul, and suffered defeat in defending that country against the Germans. He strangled himself upon hearing of the defeat and deposition of his brother by Constantius, who succeeded to the throne of Magnentius.

(_Numbers continuing at the end next to the Greek Court._) 77. TRAJAN. _Roman Emperor._ For life, see No. 45. 78. TRAJAN. _Roman Emperor._ 79. ANTINOUS. _Bithynian youth._ [Died in Egypt, A.D. 132.] Celebrated for his beauty. He was the page and companion of the Roman Emperor Hadrian, whom he accompanied to Egypt. He was drowned in the Nile, and the Emperor was inconsolable for his loss. On the spot where he died, the city of Antinœa was raised; temples and statues in Egypt and Greece were erected to his memory; and in Greece, coins were struck in his honour. The numerous representations of his beauty gave a fresh impulse to the Fine Arts, and may be compared with the works of the best periods of Grecian Sculpture.
