RENTY, Gaston-Jean-Baptiste de (1611-1649). The introduction charitable en la cosmographie. Paris: Clouzier, 1639. Rare illustrated treatise of geocentric cosmography (one passage in auction, RBH), written by Baron Gaston de Renty, eminent figure of the French spirituality of the seventeenth century, known for its intense mystical life and charitable commitment. The work combines scientific, moral and religious elements, presenting cosmography as a way of knowledge of creation and an instrument of spiritual elevation. In an era marked by the confrontation between cosmological models, the text fits into the geocentric tradition with pedagogical and devotional purposes, offering an accessible but learned synthesis of astronomical knowledge then current. 8vo, (163 x 105mm). Two parts in one volume, numerous astronomical xylographic illustrations in the text (bruniture). Coeva bonding in waiting cardboard (no back). (1)
