[Sidenote: Military system; warlike resources.] The army consisted of 200,000 men. Their weapons were bows, lances, slings, battle-axes, swords; their means of defence, shields, bucklers, helmets, and coats of quilted cotton. Each regiment had its own banner, but the imperial standard, the national emblem, was a rainbow, the offspring of the Sun. The swords and many of the domestic implements were of bronze; the arrows were tipped with quartz or bone, or points of gold and silver. A strict discipline was maintained on marching, granaries and depôts being established at suitable distances on the roads. With a policy inflexibly persisted in, the gods of conquered countries were transported to Cuzco, and the vanquished compelled to worship the Sun; their children were obliged to learn the Peruvian language, the government providing them teachers for that purpose. As an incitement, this knowledge was absolutely required as a condition for public office. To amalgamate the conquered districts thoroughly, their inhabitants were taken away by ten thousand, transported to distant parts of the empire, not, as in the Old World, to be worked to death as slaves, but to be made into Peruvians; an equal number of natives were sent in their stead, to whom, as a recompense for their removal, extraordinary privileges were given. It was the immemorial policy of the empire to maintain profound tranquillity in the interior and perpetual war on the frontiers. The philosophical advancement of the Peruvians was much retarded by their imperfect method of writing--a method greatly inferior to that of Egypt. [Sidenote: Peruvian literature--the quipus.] A cord of coloured threads, called quipus, was only indifferently suited to the purposes of enumeration, and by no means equal to hieroglyphics as a method of expressing general facts. But it was their only system. Notwithstanding this drawback, they had a literature consisting of poetry, dramatic compositions, and the like. Their scientific attainments were inferior to the Mexican. Their year was divided into months, their months into weeks. They had gnomons to indicate the solstices. One, in the form of an obelisk, in the centre of a circle, on which was marked an east and west line, indicated the equinox. These gnomons were destroyed by the Spaniards in the belief that they were for idolatrous purposes, for on the national festivals it was customary to decorate them with leaves and flowers. As the national religion consisted in the worship of the Sun, it was not without reason that Quito was regarded as a holy place, from its position upon the equator.
