[109] The sons of Augustus were Gaius, adopted in 737, died in 757; Lucius, adopted at the same time, died in 755; Agrippa Postumus, adopted in 757, exiled in 760. These were the sons of Agrippa and Julia. On the death of Gaius in 757, Augustus adopted Tiberius. With him Germanicus, nephew and adopted son of Tiberius, and Drusus, Tiberius’ own son, became the legal grandchildren of Augustus. None of these could celebrate games in his own name after adoption, as they had no property rights, but were absolutely dependent on the head of their house, according to the _patria potestas_ of the Roman law. See this very plainly set forth in Suetonius, _Tib._ 15: “After his (Tiberius’) adoption he never again acted as master of a family, nor exercised in the smallest degree the rights which he had lost by it. For he neither disposed of anything in the way of gift, nor manumitted a slave; nor so much as received an estate left him by will, or any legacy, without reckoning it as a part of his _peculium_, or property held under his father.” Tiberius was forty-six years old when he was adopted. Seven of these exhibitions can be traced. 1. In 725, on the dedication of the temple of the Divine Julius. Dio, LI, 22. 2. In 726, in honor of the victory of Actium. Dio, LIII, 1. 3. In 738, in accordance with a decree of the senate. This was in the name of Tiberius and Drusus. Dio, LIV, 19. 4. In 742, at the Quinquatria held March 19-23, in honor of Minerva. This was in the name of Gaius and Lucius. Dio, LIV, 28, 29. 5. In 747; funeral games in honor of Agrippa. Dio, LV, 8. 6. In 752, at the dedication of the temple of Mars. Vell. II, 100. 7. In 759, in honor of Drusus, in the name of his sons Germanicus and Claudius. Dio, LV, 27; Pliny, _Hist. Nat._, II, 26, 96; VIII, 2, 4. Possibly the eighth occasion may be found in Suetonius, _Aug._, 43. [110] Cf. Dio, LIII, 1; Suet. _Aug._, 43. Wooden seats were erected in the Campus Martius for gymnastic contests in 726. Whether Germanicus or Drusus is the grandson mentioned here is unknown. [111] These were the lesser games of the circus and theatres, given ordinarily by magistrates holding the lower offices, which Augustus never filled. He took upon himself the care and expense where the proper magistrates were absent or too poor. Cf. Dio, XLV, 6; C. I. L., I, p. 397. [112] The charge of the Secular Games, celebrated supposedly once in a century, though in reality oftener, fell to the quindecemvirs. Cf. Eckhel, VI. 102, for a coin with _imp. Cæsar Augustus lud. saec. XV S. F._ This was in 737. Cf. also C. I. L., I, p. 442. The college evidently gave the presidency to Augustus and Agrippa, since it was very convenient that these two members of the sacred body also held the tribunitial power, and so the games came into the charge of the two greatest men of the state in a perfectly natural way. Cf. C. I. L., IX, p. 29, No. 262, for confirmation of Agrippa’s membership in the college of quindecemvirs.
