Interesting find.

From the article: "They don't know if that was the cause of death or if the embalmers did that to keep the head steady in the sarcophagus"

My questions are these.
During the Ptolemaic era, was impaling a mummy's skull common? Are there a number of other like mummies, or is this the only one found with a spear in his or her skull? Are there any ancient texts supporting this technique for keeping the head steady?
