On the 23rd of April 1490 I began this book, and recommenced the horse.

721.

There is to be seen, in the mountains of Parma and Piacenza, a multitude of shells and corals full of holes, still sticking to the rocks, and when I was at work on the great horse for Milan, a large sackful of them, which were found thereabout, was brought to me into my workshop, by certain peasants.

722.

Believe me, Leonardo the Florentine, who has to do the equestrian bronze statue of the Duke Francesco that he does not need to care about it, because he has work for all his life time, and, being so great a work, I doubt whether he can ever finish it. [Footnote:  This passage is quoted from a letter to a committee at Piacenza for whom Leonardo seems to have undertaken to execute some work.  The letter is given entire in section XXL; in it Leonardo remonstrates as to some unreasonable demands.]

723.

Of the horse I will say nothing because I know the times. [Footnote:  This passage occurs in a rough copy of a letter to Ludovico il Moro, without date (see below among the letters).]

724.

During ten years the works on the marbles have been going on I will not wait for my payment beyond the time, when my works are finished. [Footnote:  This possibly refers to the works for the pedestal of the equestrian statue concerning which we have no farther information in the MSS.  See p. 6.]

The project of the Trivulzio monument.

[Footnote:  In the original, lines 2-5, 12-14, 33-35, are written on the margin.  This passage has been recently published by G. Govi in Vol.  V, Ser. 3a, of Transunti, Reale Accademia dei Linea, sed. del 5 Giugno, 1881, with the following introductory note:  "Desidero intanto che siano stampati questi pochi frammenti perche so che sono stati trascritti ultimamente, e verranno messi in luce tra poco fuori d’Italia.  Li ripubblichi pure chi vuole, ma si sappia almeno che anche tra noi si conoscevano, e s’eran raccolti da anni per comporne, quando che fosse, una edizione ordinata degli scritti di Leonardo."

The learned editor has left out line 22 and has written 3 pie for 8 piedi in line 25.  There are other deviations of less importance from the original.]
