Glyph origin
Disputed; a sieve and a human placenta have been proposed as possibilities. In the Archaic Period it was generally crosshatched horizontally and vertically, and this form sometimes appeared through the Old Kingdom. For most of Egyptian history through the New Kingdom a form with only horizontal striations was used. A form with diagonal striations instead was rare before the Libyan Period. In some representations that lack striations, only its color differentiates it from other circular glyphs.
