We regard with astonishment the wonderful versatility which we find displayed in Galileo’s works. And amongst them are not only all the larger ones announced in the above letter; his important telescopic discoveries and his ceaselessly active mind led him far to surpass the bounds he had set himself, for he was the first to infuse conscious life into the slumbering idea of the Copernican system. This memorable letter of Galileo’s soon brought the court of Tuscany to a decision. Fourteen days later, 22nd May, Vinta wrote to him, as a preliminary, that the Grand Duke seemed well disposed to recall him to his native country and to grant all his wishes.[60] He promised to inform Galileo as soon as it was all settled. On 5th June he wrote that Cosmo II. was willing to nominate him as first philosopher and mathematician of the University of Pisa, with an annual stipend of 1000 Florentine scudi, without any obligation to live at Pisa or to give lectures. Vinta requested Galileo to let him know whether he agreed to these conditions, in order that he might have the necessary application drawn up in Galileo’s name, as well as the decree and rescript; the time of their publication shall be left to Galileo, and meanwhile all shall be kept secret.[61] Galileo wished particularly that nothing should be known at Venice of these negotiations, which did not place his gratitude to the republic which had shown him so much favour in the best light, until all was decided and therefore irrevocable. Having declared himself entirely satisfied with the proposed conditions, in a letter to the secretary of state, the only alteration being that he should like not only to be first mathematician at Pisa, but also first mathematician and philosopher to the Grand Duke himself,[62] the decree summoning him to the court of Tuscany in this twofold capacity was issued on 12th July, 1610.
