Among the treasures in the university library in Uppsala (Sweden) is an extraordinary genealogical tree of Russia’s Rurikid rulers, beginning with the legendary Rurik and ending with Tsar Fedor Ivanovič, who died in 1598. Up to now it has not been known where it was produced, when it came into being, and who could have been the scribe of the Russian names. In this paper we argue that the genealogical tree was produced in Sweden and that the scribe for the Russian names was Aleksej Mankiev, who helped the Swedish scholar Johan Gabriel Sparwenfeld by producing fair copies of the latter’s manuscripts. Mankiev’s sojourn in Sweden from 1700 to 1718 gives us a first approximation for the date of the drawing. We think that this can be narrowed down to “around 1715”, given the close relationship between the “Uppsala tree” and the Rurikid genealogy presented in Jadro rossijskoj istorii, a manuscript which was finished in Sweden in 1715, most probably also by “our scribe”, Mankiev.
