A manuscript containing 'Leges Hoelianæ ex vetustissimo Exemplario Membranaceo Per Guilielmum Mauricium Lansilinniensem', noted as being 'fideleter Transcriptæ Annno Domini MDCLXII'. The words 'Per Guilielmum Mauricium Lansilinniensem' and 'Anno Domini MDCLXII' have been blottesquely deleted by a hand which has substituted in the margin 'in Bibliothecâ Roberti Vaughan de Hengwrt Armigeri': in other words, it is a transcript of pp. 1-47 of Peniarth MS 28. The text is beautifully written but left unfinished.
In c. 1685 the transcript was noted as being 'curâ Doct: Humphrys Decani Banchorensis'.
