Yakov Bukhvostov

Yakov Grigorievich Bukhvostov (Russian: Яков Григорьевич Бухвостов), a serf of Russian boyar Mikhail Tatishchev, designed the so-called "octagon on cube" churches in the Naryshkin Baroque mode. He was active in the 1690s in Moscow and Ryazan, where he supervised the construction of the new Dormition Cathedral in the kremlin. His tower churches in Ubory and Troitse-Lykovo "may owe something to prototypes in wooden Russian architecture". They are built of brick and decorated with profuse white stone ornamentation. A soaring white tower in front of New Jerusalem Monastery was also built from Bukhvostov's designs. Other buildings attributed to him include the Fili and Zyuzino churches. Some of the attributions are far fetched, since "there is documentary evidence of his being in charge of constructing only a handful of buildings".

The biography of Bukhvostov is largely unknown. He was a serf assigned to the village of Nikolskoe-Sverchkovo, close to Dmitrov, which belonged to Tatishchev boyars. He was first mentioned by reliable sources in 1690, when he won a concession to build monk cells in the Moiseev Monastery in Moscow (the monastery was later demolished). After completing the cells Bukhvostov, with his people, started the construction of walls and towers of the New Jerusalem Monastery in present-day Istra. The walls and towers of the monastery bear almost no decoration, something which is not typical for Bukhvostov's style. The only exception is the Church of the Entry to Jerusalem built on the top of one of the gates. This church was apparently started by Bukhvostov, but completed by Filipp Papuga and brothers Leonty and Emelyan Mikhaylov, using Bukhvostov's plans.

In December 1692, when the construction of the New Jerusalem monastery was still under-way, Bukhvostov obtained a concession to build The Assumption (Dormition) cathedral in Ryazan, where the old cathedral had collapsed. Very soon afterwards Bukhvostov got a commission from a boyar, Pyotr Sheremetev, to build the Church of the Holy Mandylion in the village of Ubory, close to Moscow. He failed to complete the church within two years, a requirement of the contract, and Sheremetev asked the authorities to place Bukhvostov under arrest. Under the imminent threat of arrest, Bukhvostov struck a deal with Sheremetev to complete the church in 1696. When he failed to do this either, Sheremetev had him arrested, but then realized that the church would never be completed with Bukhvostov in jail and asked the authorities to release him. The church in Ubory was completed in 1697, although Sheremetev was already dead.
