Presented here for the first time in years is Selwyn's edition to the Greek text of the first four books of Origen's 'Contra Celsum', the culmination of the apologetic movement of the second and third centuries and one of the great works of the early Eastern Church.

William Selwyn (1806-1875) was canon of Ely, 1833; vicar of Melbourne, 1846; and Lady Margaret Professor at Cambridge, 1855. Among his works are 'An Attempt to Investigate the True Principles of Cathedral Reform' and 'Horae Hebraicae'.
