This manuscript is a copy of only one of six extant manuscript exemplars and an old print of this work (1743) worldwide. Its author is the famous Bohemian rabbi, astronomer and mathematician R. David ben Salomon Gans (1541-1613). In his 1974 monograph about David Gans, André Neher referred to this copy as the Manuscrit de Genève. A colophon in the manuscript gives the date as 1613, but a current study on the history of the transmission of this work suggests that it is an 18th century copy.
