The ibis was considered a manifestation of Thoth, who was god of the moon, writing, wisdom and all intellectual activity. In the Late Period and Ptolemaic Period ibises were captured and bred in captivity throughout Egypt to be slaughtered, mummified, then sold as votive offerings to Thoth. The mummies were usually interred in simple vessels, but some were given ibis-form coffins. For a similar example see no. 87, p. 140 in Fazzini, et al., Art for Eternity, Masterworks from Ancient Egypt, Brooklyn Museum of Art.
