_Room 4: Regalia._--The twelfth century crown of Vladimir Monomachus; the sixteenth century crown of the Tsars of Kazan; that of Ivan Alexievich (1680) and of Mikhail Theodorovich, the Imperial crown, that of Georgia, globes, sceptres--note particularly the beautiful workmanship from the conquered kingdom of Georgia--and the orb reputed to have been presented by Basil and Constantine in 988, together with the golden chain collar and piece of the "true cross." Among these insignia, most curious are the Barmi, metal collars worn at the coronation, of which one of the earliest has the eagle, lion, griffin, and unicorn--Byzantine symbols--and excellent coloured enamel, but said to have been remade by a Moscow goldsmith in the sixteenth century. The thrones include that of ivory brought to Russia in 1472 by Sophia Paleologus; Persian throne sent to Boris Godunov, in 1605, it is studded with more than 2000 gems; the double throne of the Tsars Ivan and Peter was made at Hamburg and is so constructed that the curtain at the back might screen the Tsarevna Sophia who used to station herself there either to watch or prompt her young brothers. In a casket is the code of the Tsar Alexis on sheets of parchment. _Room 5: Plate._--To the left on entering are the enamel ware, metal, wood, ivory, and glass, household plate of Russian manufacture in the seventeenth century of which the best are those of coloured enamel and niello. The loving cup presented by the patriarch Nikon to the Tsar Alexis; a ring of the unfortunate Eudoxia (wife of Peter I.) and a number of more or less uninteresting objects of that monarch's period; and a fine numismatic collection that will attract the enthusiast. _Ground Floor: Carriages and Harness._--The state chariot sent to Boris Godunov by Queen Elizabeth, carriages with mica windows, closed carriages of the Tsaritsas, the miniature conveyance of the young prince Peter, some relics of Napoleon; portraits of the sovereigns of Russia, and the model of the palace with which Catherine II. intended to cover the Kremlin; of the old palace at Kolomenskoe. There also is the only portrait of Maria Mniszek, and a picture representing her marriage with the false Dmitri.
