Spanish title page: treatise on statics and mechanics
Later cataloguer's frontispiece identifying the manuscript and its subject
An added Spanish-language title page written in elegant calligraphy and stamped with the oval mark of the Biblioteca Nacional. A line at the very top attributes the manuscript to Leonardo, while the main inscription describes it as a treatise on statics and mechanics written in Italian and notes that the text runs in reverse, mirror script. The inscription also records an assigned year of composition and the manuscript's folio count, marking this leaf as a bibliographic frontispiece rather than part of Leonardo's autograph text.

Cataloguer's title naming a treatise on statics and mechanics
The central calligraphic inscription announces the volume as a treatise on statics and mechanics written in Italian. It adds that the manuscript is written in reverse (mirror) script and records its folio count together with an assigned date, all in the hand of a later Spanish cataloguer rather than Leonardo.
