Lower Part of a Granite Doorjamb from a Temple of Ramesses II
Dynasty 19, reign of Ramesses II (ca. 1279-1213 B.C.)
Red Granite, from Thebes, MMA Excavations
Gift of Edward S. Harkness, 1913

(From a Flicker photographer who captured the info card) "This colossal structure, erected in commemoration of one of Ramesses II's royal jubilees, consists of two offering scenes, set one above the other. In the upper scene Ramesses II is depicted presenting drink offerings to Amen-Re in the form of Kamutef "Bull of his Mother," who was identified with the fertility god Min. In the lower scene the king is making a prayer for offerings to patron of the royal jubilee."

We can see the 'sed' hieroglyph, which means 'jubilee' (Illustration via Wilkinson, Reading Egyptian Art)

"The right side is inscribed with the names and titles of Ramesses II. At the bottom of the doorjamb Ramesses III, a Twentieth Dynasty king, has roughly incised his own cartouches. These blocks, discovered in 1912-1913 by the Museum's Egyptian Expedition, were reused in the foundations of a temple begun by Ramesses IV and continued by his two successors, but never completed."
