A unique Middle English text on the seven liberal arts survives in Cambridge, Trinity College, MS R. 14.52, a manuscript of ca. 1458–85. Latin texts on the seven liberal arts were certainly in circulation in medieval England, but this text is, to my knowledge, the earliest one written in English. It thereby offers evidence of the vernacular English reader's knowledge of the arts that were the foundation of medieval university education. This text is also unique in that it includes in (...) its chapter on grammar an attempt to describe the phonetic production of the letters of the alphabet, providing the only surviving contemporary approximation of the pronunciation of medieval English, and in that it adds a chapter on the mechanical sciences, relating them as no other medieval author to the English craft guilds.
