A fire was then kindled by means of a concave mirror of polished metal, which, collecting the rays of the sun into a focus upon a quantity of dried cotton, speedily set it on fire. It was the expedient used on the like occasions in ancient Rome, at least under the reign of the pious Numa. When the sky was overcast, and the face of the good deity was hidden from his worshippers, which was esteemed a bad omen, fire was obtained by means of friction. The sacred flame was intrusted to the care of the Virgins of the Sun, and if, by any neglect, it was suffered to go out in the course of the year, the event was regarded as a calamity that boded some strange disaster to the monarchy. *31 A burnt offering of the victims was then made on the altars of the deity. This sacrifice was but the prelude to the slaughter of a great number of llamas, part of the flocks of the Sun, which furnished a banquet not only for the Inca and his Court, but for the people, who made amends at these festivals for the frugal fare to which they were usually condemned. A fine bread or cake, kneaded of maize flour by the fair hands of the Virgins of the Sun, was also placed on the royal board, where the Inca, presiding over the feast, pledged his great nobles in generous goblets of the fermented liquor of the country, and the long revelry of the day was closed at night by music and dancing. Dancing and drinking were the favorite pastimes of the Peruvians. These amusements continued for several days, though the sacrifices terminated on the first. - Such was the great festival of Raymi; and the recurrence of this and similar festivities gave relief to the monotonous routine of toil prescribed to the lower orders of the community. *32 [Footnote 31: "Vigilemque sacraverat ignem, Excubias divum aeternas." Plutarch, in his life of Numa, describes the reflectors used by the Romans for kindling the sacred fire, as concave instruments of brass, though not spherical like the Peruvian, but of a triangular form.] [Footnote 32: Acosta, lib. 5, cap. 28, 29. - Garcilasso, Com.
