Octagon on cube

Octagon on cube (also octagon on the quadrangle) is a type of architectural composition, in which a building is designed so as the upper octagon-shaped part is placed on the lower cube-shaped part. This composition has been mainly used to design Russian orthodox churches.

Initially, this architectural solution became widespread in Russian wooden church architecture. At the end of the 17th century, the style firmly established itself among architects of the Moscow Baroque. The combination of contrasting forms of this type of church gives striving upward look as dynamism is a characteristic of the Baroque style. Octagon-on-cube churches continued to be built in Russian provinces until the end of the 18th century.

Evolution of Moscow Baroque
With regard to the Moscow Baroque, there are several different types of octagon-on-cube churches. The main one is a stand-alone, multi-level church, built mainly by the Russian nobility for their suburban estates. The essential attribute of these buildings is a combination of church and bell tower in a single composition. Directly over the octagon level was arranged an open level with eight bells. This type of churches are the starting point for all other versions of the composition.

The Church of Joasaph of the Prince of India in the Tsar’s Manor Izmaylovo Moscow 1684 -1687 (?) Princess Sophia with the participation of Prince VV Golitsyn
It was rebuilt from the church in 1678-9. The principal innovation is the appearance of a well-visible chetverik, in the early monuments of the vestibules hidden by the volumes along the perimeter of the building.

An early example of an octagon type on a quad. Miserly external decorations, apparently, reflected the severity of the customer’s tastes.

Preserved almost unchanged, reproduces the non-preserved church in Petrovsky-Dalniy.

Along with the traditional laconicism – the lack of window frames, there are elements of architecture inherent in the monuments of the Naryshkin circle.

There are two variants of dating 1690-95 and 1698-1703. Abundant decorations, features of profiling parts allow talking about a later dating of the building.

Spassky church in the village Moscow region 1693 – 1697, consecrated in1700 Ya. G. Bukhvostov P. V. Sheremetyev
It was built on the model of the Assumption Church in Petrovsky-Dalniy, but in the process of construction (in 1694) the church in Fili was solemnly consecrated, therefore the customer demanded a change of composition – the construction of a four-storey church in the spirit of the Church of Filia).

Since 1693 Y. G. Bukhvostov was busy building a cathedral in Ryazan (until 1699), therefore he handed over his assistants to the contract. The church is characterized by a high quadrilateral with large windows, giving the church a tower-like appearance.

Variations: an ellipse instead of a quadrilateral
