This is a Mamluk finial, a decoration that would adorn a standard taken into battle. It would identify different units of warriors. This finial is made from steel, with a height of 51.3 cm and a width of 11.7 cm. It has the name of Sayf al-Din Tarabay on it and a quote from the Qur’an. Sayf al-Din Tarabay was a Syrian emir, who built a well known funerary complex in Cairo. Currently the item is in the Metropolitan Museum of Art, but there is not much more information there. This Mamluk finial was thought to have been a war prize from the battle of 1517 between the last of the Mamluk Sultanate and the Ottomans. The Ottomans also used finial flags, as written in the article Decorative Motifs Used on the Ottoman Flag Finials by Jaroslav Martykán. Via Google Docs.
