The official name of this representation of Christ on an ikon is Christ Pantecrator. ["Pant" from Greek "all", "crator" from Greek to hold, own or possess; thus `one who holds all.'] The wood-panel painting dates from c.1600. Several stamps on the gilt silver cover, called the `Riza,' attest to its being made in 1848 in Moscow.
The drawing of the helmet was done by Academician Alexei F. Solntsev, while the chromolithographer is due to F. Dreger. The chromolithograph technique -- the printing of color images from stone with a different stone being required for each color -- was invented in 1818 by Zahn. By 1860 the best work was done in Germany. The process was only replaced at at end of 19th century as more efficient techniques became available. Toulouse-Lautrec pioneered the use of color lithography in original composition.
Khanjar is shown with the blade and hilt as separate pieces, and one can only get an idea of its full appearance by juxtaposing the pieces. The blade is of Damascus steel, also known as "Wootz" steel. The sheath and hilt are of either gilt silver or solid gold, decorated with emeralds, rubies, pearls and turquoise. The piece was a diplomatic gift to one of the Russian Tsars c.1600-1700 and was in the Kremlin Armory collection.
