"In a highly specialized monograph, Tschohl presents methodology and analyses of Sahagún's complex report on the Aztec pochteca, or traveling merchants, of Tlatelolco. Points out pitfalls of previously published interpretations and translations. Tschohl, who spent decades in ethnohistorical research, provides a wealth of detailed descriptions of heroic campaigns, administrative functions, and ritual culture of the commercial aristocracy of the pochteca"--Handbook of Latin American Studies, v. 58.
