The pen and ink drawing on Pl. LXXII, No. 3, reminds us of
Donatello's statue of Gattamelata at Padua. However it does not
appear that Leonardo was ever at Padua before 1499, but we may
conclude that he took a special interest in this early bronze statue
and the reports he could procure of it, form an incidental remark
which is to be found in C. A. 145a; 432a, and which will be given in
Vol. II under Ricordi or Memoranda. Among the studies--in the widest
sense of the word--made in preparation statue we may include the
Anatomy of the Horse which Lomazzo and Vas mention; the most
important parts of this work still exist in the Queen's Li Windsor.
It was beyond a doubt compiled by Leonardo when at Milan; only
interesting records to be found among these designs are reproduced
in Nos. 716a but it must be pointed out that out of 40 sheets of
studies of the movements of the belonging to that treatise, a horse
in full gallop occurs but once.

If we may trust the account given by Paulus Jovius--about l527--
Leonardo's horse was represented as "vehementer incitatus et
anhelatus". Jovius had probably seen the model exhibited at Milan;
but, need we, in fact, infer from this description that the horse
was galloping? Compare Vasari's description of the Gattamelata
monument at Padua: "Egli [Donatello] vi ando ben volentieri, e fece
il cavallo di bronzo, che e in sulla piazza di Sant Antonio, nel
quale si dimostra lo sbuffamento ed il fremito del cavallo, ed il
grande animo e la fierezza vivacissimamente espressa dall'arte nella
figura che lo cavalca".

These descriptions, it seems to me, would only serve to mark the
difference between the work of the middle ages and that of the
