Dionysius Halicarnasensis, _Antiquit. Rom._ iii. 61 _sq._, iv. 74, v. 35; B. G. Niebuhr, _History of Rome_, ii. 36; Th. Mommsen, _History of Rome_, New Edition (London, 1894), i. 83; A. J. H. Greenidge, _Roman Public Life_ (London, 1901), pp. 44 _sq._ But Mommsen, while he held that the costume of a Roman god and of the Roman king was the same, denied that the king personated the god. A truer historical insight is displayed by K. O. Müller in his treatment of the subject (_Die Etrusker_, Stuttgart, 1877, i. 348 _sq._). For a discussion of the evidence see Th. Mommsen, _Römisches Staatsrecht_, 3rd Ed., i. 372 _sq._, ii. 5 _sq._; J. Marquardt, _Römische Staatsverwaltung_, ii. 566 _sq._, iii. 2nd Ed., 507 _sq._; _id._, _Privatleben der Römer_, 2nd Ed., 542 _sq._; K. O.

Among the chief passages of ancient authors on the subject are Dionysius Halicarnasensis, _ll.cc._; Strabo, v. 2. 2, p. 220; Diodorus Siculus, v. 40; Appian, _Pun._ 66; Zonaras, _Annal._ vii. 8 and 21; Livy, i. 8. 1 _sq._, v. 23. 4 _sq._, v. 41. 2, x. 7. 9 _sq._; Florus, i. 5. 6; Pliny, _Nat. Hist._ viii. 195, xv. 127, 130, 137, xxxiii. 11. 111 _sq._; Juvenal, x. 36-43; Ovid, _Ex Ponto_, ii. 57 _sq._; Macrobius, _Saturn._ i. 6. 7-9; Servius on Virgil, _Ecl._ vi. 22, x. 27; Ael.

The fullest descriptions of a Roman triumph are those of Appian and Zonaras (vii. 21). Footnote 553: Camillus triumphed in a chariot drawn by white horses like the sacred white horses of Jupiter and the Sun. His Republican contemporaries were offended at what they regarded as a too close imitation of the gods (Livy, v. 23. 5 _sq._; Plutarch, _Camillus_, 7; Dio Cassius, lii. 13); but the Roman emperors followed his example, or perhaps revived the old custom of the kings. See Dio Cassius, xliii. 14; Suetonius, _Nero_, 25; Pliny, _Panegyric_, 22; Propertius, v. 1. 32; Ovid, _Ars amat._ i. 214.
