Edward Samuel wrote some poems in free metre; for examples see (a) Blodeugerdd, 1759; (b) Llu o Ganiadau, neu Gasgliad o Garolau a Cherddi … o Gasgliad W. Jones, Bettws Gwerfil Goch (Oswestry, 1798); (c) Eos Ceiriog, 1823; and (d) B.M. Add. MS. 14961. Sermons by him were published (1731 and 1766), but his most important original work in prose was Bucheddau'r Apostolion a'r Efengylwyr (Shrewsbury, Thomas Jones, 1704, and other eds.). The following works translated by him were also published — (a) Gwirionedd y Grefydd Gristionogol (1716, etc.) — from the original by Hugo Grotius; (b) Holl Ddyledswydd Dyn (Shrewsbury, 1718); (c) Prif Ddyledswyddau Christion, sef Angenrhaid a Mawrlles Gweddi Gyffredin a Mynych Gymmuno (Shrewsbury, John Rhydderch, 1722/3; 1793 ed. printed at Chester) — from the original by William Beveridge, bishop of S. Asaph; the first of the two works, published together, was dedicated to judge Robert Price (q.v.), Giler, Denbs., and the second to Watkin Williams Wynne [sic], Wynstay [sic], and (d) Athrawiaeth yr Eglwys (Caerlleon, Roger Adams, 1731), being versions of two separate works, the one by Peter Nourse, and the other by William Wake, archbishop of Canterbury. A facsimile of a letter written by Samuel (1 March 1703/4) to Edward Lhuyd (q.v.) can be seen in Richard Ellis, Facsimiles of Letters of Oxford Welshmen.
