A manuscript, in the hand of Evan Evans (Ieuan Fardd), containing 'Cerddwriaeth Simwnt Fychan' (ff. 1-43 verso, first sequence) and the 'Rhetoreg' of William Salesbury, which was originally a translation of a Latin treatise on rhetoric (ff. 1-47, second sequence).
There are copious references to the source materials for both parts, the names mentioned including John Jones, Gellilyfdy, William Maurice and Roger Morris (ff. 1 (first sequence), 46 verso (second sequence)). A note by Ieuan Fardd states that he transcribed these works in 1776 (f. 46 verso). For Simwnt Fychan's 'Cerddwriaeth' see also Peniarth MS 159 and Jesus College MS 9.
