I will not weary you in this case, any more than in that of Mexico, with the enumeration of the authors to whom we must go for information on the political and religious history of the strange country with which we are dealing. I must, however, say a few words concerning a certain writer who long enjoyed the highest of reputations, and was regarded throughout the last century as the most trustworthy and complete authority in Peruvian matters. The Peruvians, far as their civilization had advanced in many respects, were behind even the Mexicans in the art of preserving the memory of the past; for they had not so much as the imperfect hieroglyphics known to the latter. They made use of _Quipus_ or _Quipos_, indeed, which were fringes, the threads of which were variously knotted according to what they were intended to represent; but unfortunately the Peruvians anticipated on a large scale what so often happens on the small scale amongst ourselves to those persons of uncertain memory who tie knots on their handkerchiefs to remind them of something important. They find the knot, indeed, but have forgotten what it means! And so with the Peruvians. They were not always at one as to the meaning of their ancient Quipos, and there were several ways of interpreting them. Moreover, after the conquest, the few Peruvians who might still have made some pretension to a knowledge of them did not trouble themselves to initiate the Europeans into their filiform writing. All that is left of it is the practice of the Peruvian women who preserve this method of registering the sins they intend to record against themselves in the confessional.[39] Let us hope that they at least never experience any analogous infirmity to that which besets the knot-tiers amongst ourselves.[40]
