In the mid-16th century, during the era of Tristán de Luna y Arellano and Pedro Menéndez de Avilés, everyday Spaniards commonly made use of devotional prayer books dedicated to the Blessed Virgin Mary, or Our Lady. Probate records indicate that even poorer individuals with few possessions owned such books, usually in the Spanish language (Horas en Romance), but sometimes in Latin (Horas en Latin). Digitized examples of these books are linked below for this period. Perhaps even more common in personal inventories were rosaries and strings of prayer beads, used as guides to prayer. Such beads were commonly made of wood, but were also fashioned from bone, jet, coral, crystal, jasper, amber, silver, and gold. Despite assumptions by many, glass beads seem generally not to have been used for rosaries, likely due to their fragility, but were instead most commonly noted as rescates, or trade goods.
