Latin verb endings and a red-chalk horse's head
Passive endings for the four conjugations, with a bridled horse study below
The top of the leaf carries four lines of Leonardo's Latin grammar practice, pairing the model verbs amare, docere, legere and audire with their passive personal endings. Below, in red chalk, is a study of a horse's head fitted with a bridle and harness straps, which fills the lower two-thirds of the page and is recorded in the caption as a horse's head with tack. The sheet belongs to a run of folios in Notebook H given over to Leonardo's self-taught Latin.

Passive endings for the four conjugations
Four lines set the model infinitives amare, docere, legere and audire against passive personal endings (etur; emur amini entur; atur; amur amini antur, and so on). The exercise drills how each of the four conjugations forms its passive.
Red-chalk study of a horse's head and bridle
In red chalk a horse's head is drawn in near three-quarter view, fitted with a bridle and harness straps that run down from the muzzle and cheek. The study occupies the lower two-thirds of the leaf; the caption records it as a horse's head with tack.
