[234] Two of our best portraits of Savonarola, the earlier inscribed
"Hieronymi Ferrariensis a Deo Missi Prophetae Effigies," the later treated
to represent S. Peter Martyr, are from the hand of Fra Bartolommeo. See
Crowe and Cavalcaselle, vol. iii. p. 433.

[236] This sonnet I have translated into English with such closeness to
the original words as I found possible:--

He who can do not what he wills, should try
To will what he can do; for since 'tis vain
To will what can't be compassed, to abstain
From idle wishing is philosophy.
Lo, all our happiness and grief imply
Knowledge or not of will's ability:
They therefore can, who will what ought to be.
Nor wrest true reason from her seat awry.
Nor what a man can, should he always will:
Oft seemeth sweet what after is not so;
And what I wished, when had, hath cost a tear.
Then, reader of these lines, if thou wouldst still
Be helpful to thyself, to others dear,
Will to can alway what thou ought to do.

[237] See the letter addressed by Lionardo to Lodovico Sforza enumerating
his claims as a mechanician, military and civil engineer, architect, &c.
It need scarcely be mentioned that he served Cesare Borgia and the
Florentine Republic as an engineer, and that much of his time at Milan
was spent in hydraulic works upon the Adda. It should be added here that
Lionardo committed the results of his discoveries to writing; but he
published very little, and that by no means the most precious portion of
his thoughts. He founded at Milan an Academy of Arts and Sciences, if
this name may be given to a reunion of artists, scholars, and men of the
world, to whom it is probable that he communicated his researches in
anatomy. The _Treatise on Painting_, which bears his name, is a
compilation from notes and MSS. first printed in 1651.

[238] The folio volume of sketches in the Ambrosian Library at Milan
contains designs for all these works. The collection in the Royal Library
at Windsor is no less rich. Among Lionardo's scientific drawings in the
latter place may be mentioned a series of maps illustrating the river
system of Central Italy, with plans for improved drainage.

[239] Shelley says of the poet:--

He will watch from dawn to gloom
The lake-reflected sun illume
The yellow bees in the ivy bloom;
Nor heed nor see what things th
