Birds for Isis: The evidence from Pompeii

People have always been fascinated by birds. In the Roman period, birds (particularly chicken) were still largely employed in several rituals. Although Roman writers, such as Cicero, Livy, Pliny the Elder, and Aelian, inform us about the use of birds in a number of rituals, the archaeological evidence rarely allows us to associate the collected zooarchaeological remains with a single deity. In 2017, a well-preserved archaeological context located in the vicinity of the temple of Isis in Pompeii and related to a single ritual event (dated to the mid-1st century CE), revealed a number of faunal remains as well as ceramic and archaeobotanical finds. Chicken dominates the assemblage, followed by goose, pigeon, and turtle dove. A few remains of pig and a marine bivalve, the truncate donax, were also recovered. Skeletally young chickens were largely employed in the ritual, whereas the other bird taxa are only represented by mature bones. Chicken eggshell, taxonomically identified using ancient protein analysis, was also found. Taphonomic evidence indicates that bird bones were still covered with meat when exposed to the ritual fire. The results obtained have been linked to relevant written and iconographic sources dated to the Roman period. This work confirms that bird sacrifice was an important part of the Isis rituals. Among the birds involved, goose could be considered a possible marker of that goddess. The evidence from Pompeii adds new insights into our knowledge of the animals in the Isis cult during the 1st century CE.
