When the government decided in 1822 to publish an edition of the old British historians, the Welsh portion of the work was entrusted to
John Humffreys Parry. On Parry's death in 1825 his duties came to Owen, who became the adviser of the
Public Record Office on Welsh matters. His work falls mainly under two heads – the publication of the ancient
Welsh laws, and the accumulation of material for an edition of the
Brut y Tywysogion (
Chronicle of the Princes). These tasks were carried on concurrently during the period 1830–40; and in 1841 the Record edition of the laws appeared (in two forms, a large
folio and two
quarto volumes) under the title
Ancient Laws and Institutes of Wales. It distinguished for the first time the three versions (Venedotian, Dimetian, and Gwentian) of the original
Law of Hywel. The edition of the
Brut y Tywysogion did not appear in Owen's lifetime. The short portion which ends at 1066 was edited by him for the
Monumenta Historica Britannica (1848), but the bulk of his material remained unpublished, and went to the Public Record Office on his death in 1851. When in 1860 the
Rolls Series edition of
Brut y Tywysogion appeared, under the editorship of
John Williams (Ab Ithel), the reviewer in
Archaeologia Cambrensis asserted that the text and the translation were the work of Owen, who was not mentioned in the book. In 1863 Owen's transcript and translation of the so-called
Gwentian Brut (a spurious
Glamorganshire version of the
Chronicle), with the introduction he had prepared for the
Monumenta, and a letter on the Welsh chronicles to
Henry Petrie, were printed as an extra volume by the
Cambrian Archaeological Association. ==Notes==
