The mathematical considerations which are necessary for accurately under- 

 standing the construction of the map will be found in the accompanying

Photographs of the Tribune of Galileo. 



The Royal Institute of " Studii Superiorly Florence. 



1 . A view of the whole Tribune of Galileo. Galileo's statue was sculptured 

 by the Professor Aristodemo Gostoli. In the lunette at the end is represented 

 Galileo while presenting his telescope to the Venetian Senate. The four 

 greater instruments that can be observed in the angles of the middle part of *the 

 tribune are, at the right hand the odometer of the Accademia del CimentOj 

 and the lens of Benedetto Bregaus, at the left hand a Florentine astrolabe 

 and the quadrant of Rinaldini. The other parts of the tribune are explained 

 in the special photographs. 



2. The left side of the further end of the tribune. The lunette represents 

 Galileo observing the oscillations of the lamp in the Cathedral of Pisa. The 

 busts are those of Benedetto Castelli and Bonaventura Cavalieri, disciples of 

 Galileo. The shelf contains the two telescopes of Galileo, and the broken 

 object-glass. 



3. The right side of the further end of the tribune. The lunette represents 

 Galileo blind, dictating to his disciples Torricelli and Viviani the geometrical 

 demonstration of the law of the fall of heavy bodies. The busts are those of 

 Evangelista Torricelli and Vincenzo Viviani. The shelf contains the natural 

 magnet armed by Galileo, his compass of proportion, the first design con- 

 ceived by him of the application of the pendulum to clocks, and the first 

 finger of his hand. 



4. Left side of the middle part of the tribune. The lunette represent* 

 Galileo who, helped by his disciples, repeats the famous experiments on the 

 uescent of heavy bodies on an inclined plane. The shelves contain various 

 ancient instruments, partly of the Accademia del Cimento. 



5. Right side of the middle part of the tribune. The lunette represent a 

 seance of the Accademia del Cimento in which the experiment is being made to 

 prove whether the cold of ice can be reflected by a mirror, like the heat of 

 burning coals and light. The shelves contain ancient instruments, partly of 

 the Accademia del Cimento. 



6 and 7. Represent two shelves with ancient instruments, partly belonging 

 to the Accademia del Cimento.
