An extremely interesting manuscript - probably the smallest Welsh manuscript in existence, though it is 1.5 inches thick - which was written by Thomas Evans, Hendreforfudd, 1618-1622, and consists mostly of prayers and englynion.

This is probably the volume referred to by Gweirydd ap Rhys in Hanes Llenyddiaeth Gymreig, pp. 402-3; it is not mentioned in Angharad Llwyd's Catalogue of the Pengwern MSS (Transactions Cymmrodorion, 1828, p. 50).
