The early nineteenth century witnessed a remarkable reversal of judgment on the American pre-Columbian cultures. Prescott's romantic histories and Lord Kingsborough's monumental Mexican Antiquities are inspirations of earlier and less sceptical eras. Such pleasing imaginings as that the Spaniards ‘overthrew in Mexico a greater civilization than their own’ received scant support from the archaeologist who had displaced the antiquary, or from the critical historian who interpreted him. Dr Robertson1 summed up the verdict of the new investigators;:—‘The inhabitants of the New World were in a state of society so extremely rude as to be unacquainted with those arts which are the first essays of human ingenuity in its advance towards improvement’. He characterized Cortes's ‘emperors’ as ‘headmen’, the gorgeous palaces of the Conquest as ‘huts or mounds of rubble’, the Aztec Empire as a ‘league of primitive tribes’. Research, both among the ruins of the Mexican Valley and in the histories of the more prosaic conquistadores, established a singular lack of anything on the pre-Columbian continents which could be described as other than a tawdry barbarism.
