| Abstract: | Many clues lead to the conjecture that Brunelleschi knew about the use of the astrolabe, an instrument very often used in his times; among his friendships we find the astronomer Paolo Dal Pozzo and engineer Mariano di Jacopo da Siena, who certainly knew how to use the astrolabe accurately. Because this instrument is based on the principle of stereographic projection, a particular kind of central projection, it is quite possible that Filippo applied this principle for the perspective construction outline for Masaccio’s Trinità in S. Maria Novella, as well as for the two lost panels of the Baptistery of Florence. |
