MOSCOW (RUSSIAN: MOSKVA) — Currently the capital of the modern Russian Federation, Moscow was founded in the twelfth century by Prince Yury Dolgoruki. Long eclipsed by cities such as Vladimir, Tver, Suzdal, and Kiev, Moscow rose to prominence after the Mongol invasion, under the leadership of a series of competent and enterprising Rurikid princes.

MOSKVA RIVER — River along which Moscow was founded.

MUSCOVY — Derived from Latin Moscovia, from the original Russian appellation Moscov, the term refers to the Grand Duchy or Grand Principality of Moscow; for centuries, Muscovy was a common way to refer to Russia in the West. Originally Muscovy covered a relatively modest territory stretching north and east from Moscow, but from the late fourteenth to the early sixteenth century it grew enormously, until by 1505 it covered almost a million square miles.

NEGLINNAYA RIVER — Moscow was originally built on a hill between the Moskva and the Neglinnaya, and the two rivers formed a natural moat. The Neglinnaya is now an underground river in the city of Moscow.

OLEG OF RYAZAN — Also Oleg Ryazansky. The Grand Prince of Ryazan during the latter half of the fourteenth century. His role in the time leading up to the Battle of Kulikovo, and in the battle itself, is ambiguous. Some sources put him fully on the side of the Tatars. Others say he tried to play both sides, so as to come out ahead whoever won. He might have been the first one to bring word to Dmitrii that Mamai’s forces were advancing on Kulikovo; he might have delayed his own arrival at the battle and turned aside Mamai’s reinforcements to give Dmitrii a chance. He might have allowed his boyars to fight on the side of the Russians but hung back himself.

OTCHE NASH — Our Father, the opening phrase of the Lord’s Prayer in Old Church Slavonic. Even today, the prayer is generally memorized and said in this older form rather than in modern Russian.

OVEN — The Russian oven, or pech’, is an enormous construction that came into wide use in the fifteenth century for cooking, baking, and heating. A system of flues ensured even distribution of heat, and whole families would often sleep on top of the oven to keep warm during the winter.

PATENT — A term used in Russian historiography for official decrees of the Golden Horde. Every ruler of Rus’ had to have a patent, or yarlyk, from the Khan giving him the authority to rule. Jockeying for the patents of various cities made up a good deal of the intrigue between Russian princes from the thirteenth century on.

POLUDNITSA — Lady Midday, sister to Lady Midnight, who wanders the hayfields and causes heatstroke with her cutting shears.

POLUNOCHNITSA — Literally, midnight woman; Lady Midnight, a demon that comes out only at midnight and causes children’s nightmares. In folklore, she lives in a swamp, and there are many examples of charms sung by parents to send her back there. In The Winter of the Witch, this folkloric character is associated with Night, the servant of Baba Yaga in the fairy tale Vasilisa the Beautiful.
