A volume containing a Latin text of the Laws of Hywel Dda transcribed, [1625x1632], by George William Griffith of Penybenglog, Pembrokeshire, from Merton College Oxford MS 323 which was then in the possession of the mathematician, astrologer and antiquarian Thomas Allen, Gloucester Hall and Trinity College, Oxford (see R. M. Thomson, A Descriptive Catalogue of the Medieval Manuscripts of Merton College, Oxford (Cambridge, 2009), p. 248). It is one of thirteen surviving manuscripts containing the Latin text of the Welsh laws which belongs to redaction E as distinguished in Hywel D. Emanuel, The Latin Texts of the Welsh Laws (Cardiff, 1967), pp. 408-517.
The title-page, written in red and black inks, has a decorative initial 'H' with a miniature depicting Hywel Dda enthroned. The scribe writes a neat secretary hand reserving his legal hand for headings and Welsh words.
