First edition in Italian of Gafurius’s key musical treatise originally published in Latin in 1496. Gafurius was a composer but is chiefly known for his work on musical theory. He lived and worked in Milan at the court of Ludovico Sforza, where he got to know Da Vinci and is most probably the subject of Da Vinci’s “Ritrato di Musica” now in the Pinacoteca Ambrosiana. Music is one of my great passions, so I try when possible to find books about it from the period. The illustrations are rather fun!
