Funerary Cones

Funerary Cones are pottery cones that are found quite commonly in Theban tombs of the Middle Kingdom to Late Kingdom Period.
They have a flat circular or rectangular base bearing an impression of a stamp, usually with the official titles and name of the tomb owner.
Funerary cones are clay cones that were inserted above a tombs entrance usually in the space between the top of the doorway and the ceiling with the name and title of the deceased. Clay funerary cones originally decorated the mudbrick facades of private tombs at Thebes. It is thought by some that they were embedded in rows to form friezes and may have been intended to represent the ends of roof beams. The flattened base of each cone, which was all that remained visible, was stamped with the titles and name of the tomb owner.
A more commonly held theory between archaeologists is that they (and funerary cones are usually found here) were imbedded in the section of wall above the door and were used to name the tomb owner and acted sort of like a house name in that they told you to whom the tomb belonged. Most of the above information was noted down from the three following web pages, unfortunately without permission but alas I could not get in contact with the owners of the WebPages.
