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.
Bound up between pp. 12 and 13 is a copy of an early edition of the Llyfr Plygain or Primer, dated 1618 and containing 42 pp. but imperfect as it contains none of the prayers, litany or psalms. 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).
