TYCHO'S LIFE FROM HIS LEAVING HVEEN UNTIL HIS ARRIVAL AT PRAGUE (1597–1599).

When Tycho arrived at Copenhagen in April 1597, he probably did not intend to make a long stay there, but merely to watch events for a short time. He can hardly have intended to settle in his house at Copenhagen and continue his work there, as he had the Isle of Hveen for life, and might as well have stayed there if he had any wish to remain in Denmark, unless, indeed, the troubles at Hveen had risen to such a height that the island had become odious to him. He had brought his instruments, chemical apparatus, and printing-press with him, but he does not appear to have commenced astronomical observations at the tower on the rampart close to his house.

See also a letter to Vincenzio Pinelli of Padua (Aus T. Brahe's Briefwechsel, p. 12).
