Corn Mummy of Osiris

During the mysteries, two statuettes of Osiris were manufactured: one was the Osiris called vegetans, made of silt and grains that were meant to germinate, thereby illustrating the rebirth of nature; the other one was made of silt, resins and ground precious stones, and was called Osiris-Sokaris. 

Both statuettes were swaddled according to the required rituals, and deposited in a temporary tomb before being set into their permanent one at the end of the mysteries of the following year.

Sarcophagus: sycamore wood, figurine: earth and grain. Third Intermediate Period, 21st to 25th Dynasty, ca. 1069-664 BC. Now in the Egyptian Museum, Cairo. JE 36539
