The Royal Library holds many of the same books which Shakespeare used for inspiration and source material. This Latin grammar is one of the books which was most influential. Lily’s 'A Short introduction of grammar' was used to teach grammar school pupils from 1515 to 1758. Though this copy is from after Shakespeare died, it is the same text as that from which he would have been taught. Indeed, a section from it is quoted verbatim in 'The Merry Wives of Windsor', as is part of the extensive added manuscript annotations which show the teacher’s questions and the pupils’ responses for learning by rote. Lily's 'Grammar' contained quotations from classical authors to illustrate various points of learning, and from this Shakespeare found source material for his characteristic figures of speech and manipulation of language. Shakespeare's knowledge of Lily's 'Grammar' and of grammar-school learning methods are evidence that he attended a grammar school himself. If he were an aristocrat using an assumed name, as some have asserted, he would have had a private tutor, and little knowledge of grammar schools.
