Description: Bianchini was a renaissance astronomer affiliated with the Vatican. He is known best for his studies of Venus. His deduction of a rotational period of Venus was based on the observation of its surface using a 2.6" (66mm) 100-foot focal length aerial telescope. Today, we know that this is impossible, because of the thick cloud cover on this planet. He also worked on the parallax of Venus, and he measured the precession of the Earth's rotational axis. As part of his efforts to improve the accuracy of the calendar, Bianchini was commissioned by Clement XI to construct an important meridian line in the Basilica of Santa Maria degli Angeli e dei Martiri (the Basilica of Saint Mary of the Angels and the Martyrs) in Rome, a device for calculating the position of the sun and stars.
