Yny lhyvyr hwnn

It was written by Sir John Price of Brecon, a nobleman and secretary of the Council of Wales and the Marches.

As Yny lhyvyr hwnn was a Renaissance humanist venture with the aim to put into print the heritage of Welsh literature, Price also included an ABC section and the first Welsh printed alphabet.

A record of English, European and Welsh saints was added, as well as a monthly forecast for agricultural purposes.

The last section of the pamphlet is a comprehensive religious text, approximating contemporary primer prayer books but sans the canonical hours.

It was part of the foundation collection donated by Sir John Williams to the Library in 1908.
