⚠️ Disputed: the sources disagree.

What it is

The first printed treatise on the education of the deaf: it sets out an oralist method based on a one-handed manual alphabet, illustrated with engravings, and on learning pronunciation letter by letter.

Bonet was accused of drawing on the method of Manuel Ramírez de Carrión, whom he had assisted; Ramírez's book (Maravillas de naturaleza, 1629) is later but his practice earlier. The diffusion of Bonet's manual alphabet is well documented.

What it led to

  • a fingerspelling alphabet that inspired later manual alphabets
  • oralism in the education of the deaf in the 17th-18th centuries
  • European diffusion of the method (Wallis, Amman, De l'Épée)
