A hornbook (horn-book) is a single-sided alphabet tablet, which served from medieval times as a primer for study,[1] and sometimes included vowel combinations, numerals or short verse.[2] The hornbook was in common use in England around 1450,[3] but may have originated more than a century earlier.[4] The term (hornbook) has been applied to different study materials in different fields but owes its origin to children's education, represented by a sheet of vellum or paper displaying the alphabet, religious verse, etc., protected with a translucent covering of horn (or mica) and attached to a frame provided with a handle.[5]
