[Of Squaring the Circle} 
1509, April 28 

Having for a long time sought to square the angle of two curved 
sides, that is the angle e, which has two curved sides of equal curve, 
that is curve created by the same circle: now in the year 1509, on the 
eve of the calends of May, I have solved the proposition at ten o'clock 
on the evening of Sunday. I know therefore (as is shown on the reverse 
of this page A) that the surface a b taken from its position and given 
the same value with the portion c as the rectilinear triangle d c corre- 
sponds exactly to the curvilinear triangle e c, I would call it the 
curvilinear triangle a b d. Therefore that square of the triangle e will 
be found in the rectilinear triangle c d.

according to Calvi, between 1504 and 1506, Leonardo refers to the multitude of shells 
and corals sticking to the rocks which are to be seen in the mountains of Parma and 
Piacenza. The passage has the air of being based on first-hand knowledge. If the 
suggestion campagna be accepted it might be that Leonardo was revisiting some of his 
old haunts. The text, however, really only establishes his presence at Parma on the date 
mentioned. As such, it proves that his stay in Rome was interrupted. Dated references 
attest his presence there on the seventh of July 1514, and as late as August 151 6. 
The visit to Parma may possibly have been connected with the fact that Parma was one 
of the papal cities of which Giuliano de' Medici, Leonardo's patron in Rome, had been 
made the governor.
