His supplying grain as well as money rose from the fact that taxes were imposed both in kind and in money. Cf. Tac. _Ann._ IV, 6; _Agr._ XIX and XXXI; C. I. Gr. 4957, 47. These passages all speak of taxes both in money and in produce. As to the method of levy, Hyginus is interesting (_De Lim._ p. 205). “The tax on agriculture is arranged in many ways. In some provinces the harvest is chargeable with a certain proportion, here a fifth, there a seventh, elsewhere a cash payment, and for this purpose certain values are determined for the fields by an estimation of the soil; as in Pannonia there is arable of the first class, of the second, meadows, mast-bearing woods, common woods, pastures: upon all these the tax is laid by the single acre, according to the fertility of the soil.” This was in the time of Trajan. [84] The structures detailed here and in cc. 20 and 21, fall into three classes. First, those of c. 19, being either new buildings in place of ruined ones, or else entirely new ones, both classes on soil already consecrated; second, those of c. 20, being repairs of public works; third, public works upon soil given by himself, as noted in the first part of c. 21. Augustus does not mention structures which he erected in the name of others, as the portico of Octavia, (different from the one below, Note 90), the portico of Livia, cf. Dio, XLIX, 43 and LIV, 23. He also omits the temple of Concord dedicated by Tiberius in 763 (C. I. L. I. p. 384), though he paid for it. The order of the works is chronological for the most part. [85] This was the Curia Julia, begun in 712. Cf. Dio XLVII, 19; XLIV, 5; XLV, 17. It was dedicated in 725 after Actium. Cf. Dio LI, 22. Here the senate met. Its location was near the forum. [86] A shrine of Minerva Chalcidica. [87] Begun after the Sicilian victories in 718. Cf. Dio XLIX, 15; Vell. II, 81, dedicated Oct. 9, 726. Cf. Dio, LIII, 1; C. I. L. I, p. 403. Suet. _Aug._ 29, says: “He reared a temple of Apollo in that part of his estate on the Palatine which the haruspices declared was desired by the god because it had been struck by lightning; he attached to it a portico and a Greek and Latin library.” [88] An altar was placed at once on the spot in the forum where the body of Julius Cæsar was cremated. In 712 the senate decreed that a temple should be built there. [89] Dionysius (I, 32), observes that the ancient condition of this place (originally a grotto near the Palatine, sacred to Pan) had been so changed as to be hardly recognizable. This was by reason of the changes made in his time, which nearly coincided with that of Augustus. Cf. C. I. L. VI, 912, 6, 9, and 841. Its precise location is undetermined.
