Diego de Landa, Account of the Things of Yucatán (mid-1560s), on trade and farming, and on the Maya books · written in the mid-1560s (describes Maya life before and after the Spanish conquest, as Landa knew it from 1549)
El officio en que mas inclinados estavan es mercaderia, llevando sal, ropa y esclavos a tierra de Ulua y Tavasco, trocandolo todo por cacao y cuentas de piedra que era su moneda, y con esta solian comprar esclavos o otras cuentas con razon que eran finas y buenas, las quales por joyas trayan sobre si en las fiestas los señores. Y tenian otras hechas de ciertas conchas coloradas por moneda y joyas de sus personas. Y lo traian en sus bolsas de red que tenian y en los mercados tratavan de todas quantas cosas avia en essa tierra. Fiavan, prestavan, y pagavan cortesmente y sin usuras.
The trade they liked best was commerce. They carried salt, cloth, and slaves to the lands of Ulua and Tavasco and traded it all for cacao and stone beads, which were their money. With these they bought slaves, or finer and better beads, which the lords wore as jewels at feasts. They also had money made of certain red shells, which they wore as jewelry too. They carried their money in net bags. In the markets they traded in everything there was in that land. They sold on credit, lent, and paid back honorably and without usury.
