The African sacred ibis (Threskiornis aethiopicus) was revered by the Ancient Egyptian as a manifestation of the deity Thoth – The Egyptian deity of wisdom, writing, and magic. This type of bronze figurine is often found at the cult centres of Thoth (such as Hermopolis) and they are often identified as being from the Late Period of Egypt.
Some of these figurines are attached to a lid of an ibis mummy coffin, such as the one in Brooklyn Museum (Accession Number 37.417E). Others are found as a standalone object with a base, such as “Ibis on a wooden base” at the Metropolitan Museum of Art, New York (Accession Number 04.2.462); or “Solid-cast copper alloy figure of an ibis” at the British Museum (Accession Number EA11619). Another example from Australia is the bronze ibis figurine at the South Australian Museum, Adelaide (Accession Number A40053).
This bronze ibis figurine of unknown provenance is currently located at the Museum of Ancient Cultures in Macquarie University (Accession Number MU 4810) .
