Member of the House of Habsburg (1552–1612) who ruled as Holy Roman Emperor from 1576 to 1612. LS, in Latin, one page both sides, 8.5 x 12.5, September 15, 1592. Untranslated letter in Latin, which is addressed to Cardinal Montelparo, and countersigned by both Rudolph’s private counselor Johann Barwitz, a noted Catholic humanist, and his chancellor Jacob von Kurz Senftenau—both highly cultured officials who both supported astronomers Tycho Brahe and Johannes Kepler (the latter having dedicated one of his works to Barwitz). Reverse of second integral sheet bears a near-complete embossed paper seal. In very good condition, with partial separation to adjoining fold and moderate scattered foxing, toning, and soiling. An evocative document of a brilliant court by its ruler and two of its most active players. RR Auction COA.
