In comparison to males, little is known about everyday life in femalemonastic communities, and how it has changed over time. In this paper, we present a paleodietary (δ13C and δ15N in bone collagen)study of human (n = 58) and animal (n = 13) remains recovered from the former Convent of Santa Catalina de Siena in Belmonte(Cuenca, central Spain). Two funerary areas used by Dominican nuns were sampled: one dated to the sixteenth (n = 34) and theseventeenth (n = 15) centuries, and the other dated in the nineteenth and twentieth (n = 9) centuries. The isotopic values for sheep(n = 7) suggest the animals consumed at the convent came from diverse ecosystems or were raised under a range of managementstrategies. The human samples reflect a terrestrial diet, and those from the nineteenth to twentieth century, in some cases, reveal thepresence of C4 plants (millet, corn or sugar cane). Due to their religious practice, the consumption of terrestrial animal protein wasrestricted, and although they were allowed to eat fish, the isotopic signatures show little evidence of this. The individuals from thesixteenth and seventeenth century show a continuous shift in δ15N (9.7–12.7‰), with few significant differences in relation to theperiod, age, or pathologies (osteoporosis, periostitis, and brucellosis). The nineteenth- to twentieth-century samples can be divided intotwo groups: (a) one that fits the trend of previous centuries, albeit with a higher δ15N, possibly related to extensive access to animalprotein; and (b) a second group with elevated δ13C values (up to − 15.7‰). Different customs in the assumed homogeneous monasticlife are discussed as possible sources of isotopic variation, including access to luxury products such as animal protein or sugar, or thepractice of periods of food abstinence, which were especially popular with these communities, according to historical records.
