Ondegardo's writings are honorably distinguished by freedom from that superstition which is the debasing characteristic of the times; a superstition shown in the easy credit given to the marvellous, and this equally whether in heathen or in Christian story; for in the former the eye of credulity could discern as readily the direct interposition of Satan, as in the latter the hand of the Almighty. It is this ready belief in a spiritual agency, whether for good or for evil, which forms one of the most prominent features in the writings of the sixteenth century. Nothing could be more repugnant to the true spirit of philosophical inquiry or more irreconcilable with rational criticism. Far from betraying such weakness, Ondegardo writes in a direct and business-like manner, estimating things for what they are worth by the plain rule of common- sense. He keeps the main object of his argument ever in view, without allowing himself, like the garrulous chroniclers of the period, to be led astray into a thousand rambling episodes that bewilder the reader and lead to nothing. Ondegardo's memoirs deal not only with the antiquities of the nation, but with its actual condition, and with the best means for redressing the manifold evils to which it was subjected under the stern rule of its conquerors. His suggestions are replete with wisdom, and a merciful policy, that would reconcile the interests of government with the prosperity and happiness of its humblest vassal. Thus, while his contemporaries gathered light from his suggestions as to the present condition of affairs, the historian of later times is no less indebted to him for information in respect to the past. His manuscript was freely consulted by Herrera and the reader, as he peruses the pages of the learned historian of the Indies, is unconsciously enjoying the benefit of the researches of Ondegardo. His valuable Relaciones thus had their uses for future generations, though they have never been admitted to the honors of the press. The copy in my possession, like that of Sarmiento's manuscript, for which I am indebted to that industrious bibliographer, Mr. Rich formed part of the magnificent collection of Lord Kingsborough,--a name ever to be held in honor by the scholar for his indefatigable efforts to illustrate the antiquities of America.
