Note 40 — Chapter I · ANCIENT MEXICO—CLIMATE AND PRODUCTS—PRIMITIVE RACES—AZTEC EMPIRE

Clavigero, Stor. del Messico, tom. i. lib. 2.—Torquemada, Monarch. Ind., tom. i. lib. 2.—Boturini, Idea, p. 146.—Col. of Mendoza, Part 1, and Codex Telleriano-Remensis, apud Antiq. of Mexico, vols. i., vi.—Machiavelli has noticed it as one great cause of the military successes of the Romans, “that they associated themselves, in their wars, with other states, as the principal,” and expresses his astonishment that a similar policy should not have been adopted by ambitious republics in later times. (See his Discorsi sopra T. Livio, lib. 2, cap. 4, apud Opere (Geneva, 1798).) This, as we have seen above, was the very course pursued by the Mexicans.
