The Danish Crown’s Indemnity to Tycho Brahe for the Buildings and Instruments of Uraniborg 1588
In the spring of 1588, shortly after the death of his patron Frederick II, Tycho Brahe petitioned the regency government of the eleven-year-old Christian IV, showing that he had sunk his pensions and the income of his hereditary estate into the buildings and works on the island of Hveen and had run up a debt of 6,000 daler. Chancellor Niels Kaas and Jørgen Rosenkrantz visited him on the island on 8 July; four days later the King, with the Privy Council’s sanction, granted the whole sum, 2,000 daler from the Treasury and 4,000 from the crown revenue of the dissolved Dueholm monastery, and it was paid that December out of the Sound dues at Elsinore. The money bundles design and execution together — the laying out of Uraniborg, the sunken observatory of Stjerneborg finished in 1584, the brass and steel quadrants and armillae built in Tycho’s own workshops, and the printing house and paper mill he ran on the island — against an annual income he put at about 2,400 daler, so the indemnity came to some two and a half years of everything the crown gave him. Conversion is by silver content at the bimetallic ratio of the 1580s and is therefore an estimate; Hveen passed to Sweden in 1658, but the petition, the grant and the payment were all Danish.
