In the early middle ages Wales was divided in seveal kingdoms, each with its own laws. Hywel ap Caell, usually known as 'Hywel Dda' or Hywel the Good, who became king over nearly all of Wales in 942, is credited with having brought these different systems into a single body of law, although three different versions exist: for Venedotia (north Wales), Dimetia (south Wales), and Gwent (south-east). The Law contnued in use in Wales until the union with England in 1536. Compiled by legal professionals, a book such as this would have been written out by professional scribes. Those using it would have travelled a circuit of courts rather than being permanently based in one place. This page concerns land suits and shows two different scripts or styles of handwriting, possibly indicating a later addition to the book. In the lower margin, the book's 18th-century owner has written his name, "Robert Thomas of Lanfair, Talheirn, Co. Denb., 1746."
