Large sized blue & black faience wedjat (eye of Horus) amulet. Longitudinally pierced for suspension. Ex Sams collection (187).
Dated by Professor Percy Newberry to Dynasty 22 however, communication with Dr Luca Miatello in October 2014 would suggest this is innacurate: "It seems to me that the triangle under the horizontal line of the eye is a feature of the Late/Greco-Roman period.
I am studying that iconographic feature and I didn't find another example of udjat-eye with that triangle from the Third Intermediate Period or New Kingdom, so far."
