_Sir Thomas Malory, Knt._--I should feel obliged if any of your correspondents could give me any information relative to Sir Thomas Malory, Knt., who translated into English _The most Ancient and Famous History of the renowned Prince Arthur, King of Britaine_? Also any particulars relative the original author of that work? M. P. S. Inverness. [Consult Herbert's edition of Ames's _Typographical Antiquities_, vol. i. pp. 59-61. 134.; Dibdin's _Typographical Antiquities_, vol. i. pp. 241-255.; and Wharton's _History of English Poetry_.] _Archbishop of Spalatro._--In a note to the account of Chelsea College, in Lysons' _Environs of London_, which contains a list of the first fellows of the college, called by Archbishop Laud "Controversy College," of which Dr. Sutcliffe was founder and provost, I read-- "Many vacancies having occurred by the promotion of some of the fellows above-mentioned to bishoprics, and by the death of others, King James, by his letters patent, Nov. 14, 1622, substituted others in their room, among whom was _the celebrated Archbishop of Splalato, then Dean of Windsor_." I wish to ask who this archbishop was? and should be glad to learn any further particulars respecting him, especially as to whether he ever acted as a bishop in England? _Splalato_ is, I presume, an error of the press for _Spalatro_. W. FRAZER. [Mark Antony de Dominis, born about 1561, was educated among the Jesuits, and was Bishop of Segni, and afterwards Archbishop of Spalatro. Bishop Bedell met with him at Venice, and corrected, previous to publication, his celebrated work _De Republica Ecclesiastica_. When Bedell returned to England, Dominis came over with him. Here he preached and wrote against the Romanists, and the king gave him the Deanery of Windsor, the Mastership of the Savoy, and the rich living of West Ildesley in Berkshire. De Dominis's wish seems to have been to re-unite the Romish and English churches. He returned to Rome in 1622, where he abjured his errors, but on the discovery of a correspondence which he held with some Protestants, he was thrown into prison, where he died in 1625. He was a man of great abilities and learning, although remarkable for a fickleness in religious matters. He was author of a work entitled _De Radiis Visus et Lucis in Vitris Perspectivis et Iride Tractatus_, and was the first person, according to Sir Isaac Newton, who had explained the phenomena of the colours of the rainbow. We are also indebted to him for Father Paul's _History of the Council of Trent_, the manuscript of which he procured for Archbishop Abbot.--See Chalmers's _Biographical Dictionary_, _s.v._ DOMINIS.]
