 In her second single-author monograph, "Transatlantic Ties", Altman focused on two particular localities, the textile-producing Spanish town of Brihuega and Mexico's second-most important colonial city, Puebla de los Angeles.She traced social and economic networks, as well as cultural continuities and discontinuities in the late sixteenth and early seventeenth centuries.Puebla was a natural way-station between the port of Veracruz and the viceregal capital, Mexico City, but it developed as a rich agricultural zone and as a locus for textile production for a colonial mass market.
