Domostroy (Russian: Домострой, IPA: [dəmɐˈstroj], Domestic Order) is a 16th-century Russian set of household rules, instructions and advices pertaining to various religious, social, domestic, and family matters of the Russian society. Core Domostroi values tended to reinforce obedience and submission to God, Tsar and Church. Key obligations were fasting, prayer, icon veneration and the giving of alms.
Its real author is unknown, but the most widespread version was edited by the archpriest Silvester, an influential advisor to young Ivan IV. The text does include an epistle entitled "64. A Father's Epistle Instructing His Son," which was written by Silvester instructing his son, Anthemius, on some of the larger themes found within the Domostroi. An updated edition of the Domostroi was compiled by Karion Istomin during the late 17th century. To modern researchers, it is a precious account about Russian society and the life of wealthy boyars and merchants.
Modern researchers tend to trace the origins of the Domostroy to the 15th century Novgorod Republic, where it could have been used as a kind of moral codex for the wealthy. As such, it has some quotations from the Book of Proverbs and other biblical texts, and from earlier Russian morale texts such as Izmaragd and Zlatoust, and from some western texts such as Book of Christian teachings (Czech) and Le Ménagier de Paris (French).
