| Titolo: | The Galilean jovilabe / Silvio A. Bedini. |
| Abstract: | The jovilabe is an astronomical instrument first designed by Galileo to serve as a ready reckoner for calculating the positions of the four satellites of Jupiter which he had discovered. He used it for compiling his ephemerides, and visualized its potential as another device useful for determining the longitude at sea by means of observations of the Jovian satellites. Versions of the jovilabe were devised by a number of the later astronomers for use in their own astronomical observations, but it was never commercially produced. A curious example of the instrument, which forms the subject of this paper, made of gilt brass several decades after the death of Galileo, was found among the possessions of Cardinal Leopold de' Medici in 1675. Based on Galileo's original "Giovilabio", it survives not only as a historic object from a seventeenth century "cabinet of curiosities", but also as a relic of Galileo's long and fruitless quest for a solution to the determination of the longitude at sea |
