Another notable item listed in the Household Treasure is the Crown of István Bocskay. This Transylvanian prince sided with the Ottoman Turks during their wars with the Habsburg empire. As a sign of their gratitude, the Ottomans sent him a crown, probably a Persian production from the 17th century. After his death, it was brought to Vienna in 1609. It is made out of gold, studded with precious stones and pearls, and laid in with silk. As crowns were not in use in the Ottoman Empire, it was modeled after the Byzantine (closed bonnet-like headdress), similar to those used in the Orthodox church. The crown has two main parts: a broad circlet with a wreath of fleurs-de-lis and a closed, spherical helmet rising from it. The frontal lily bears a Greek cross.
