A number of infant burials in Britain, both cremations and inhumations, contained a consistent deposit of a small jet bear, black mineral jewellery, a coin, and a pottery beaker. Some of the graves held several examples of these items, and some a wider variety of objects. Comparison with more obviously amuletic grave deposits from Butt Road, Colchester, and Lankhills, Winchester, suggests that the coins were selected for their reverse image, and that both they and the bears are representations of guardians placed in the burials to ensure that the child did not enter the underworld alone and unprotected. These bears are set in the wider context of the animal's iconography and mythology, with particular reference to the Greek cult of Artemis, who oversaw childbirth and child-rearing. The choice and importance of materials and the positions of objects within graves are also briefly explored and the social identity of the dead infants is examined. In an appendix of other burials containing jet animals, the Chelmsford hoard of jet jewellery is reinterpreted as grave goods from the inhumation of a young woman.
