_Royal "We."_--Can you inform me when, and under what circumstances, the use by royalty in Europe sprung up, of using the plural "we" instead of "I," the first person singular? FRANCIS J. GRUBB. _Gondomar._--Mr. Macaulay, in one of his "Essays," remarks, "The skill of the Spanish diplomatists was renowned throughout Europe. In England the name of Gondomar is still remembered." True, oft have I heard of thee, Count Gondomar, and have read from time to time divers anecdotes of thy wit and wisdom, quips and quiddities. But is it not passing strange that this man, this Spanish Don, who, as is well known, exercised such a powerful influence over the weak-minded "Solomon of Whitehall," and who, moreover, bore so large a share in the murder of the brave and highly gifted Raleigh, should be excluded from a niche in the biographical temple; for such I am told is the case. Having deputed a friend to make search for me in the several biographical dictionaries, he reports that the name of Gondomar is _not_ to be found in the best book of the kind, the _Biographie Universelle_, nor in the dictionaries of Rose and Chalmers. This desideratum will, I confidently hope, ere long be supplied through the medium of "N. & Q.," by some of its learned contributors. W. STANLEY SIMMONDS. _Wallington's Journal._--At the sale of the library of Mr. Joseph Gulston, 1784, was sold a Journal of Mr. Nehemiah Wallington, a Puritan divine, written in the year 1630. This volume probably contains some curious matters respecting the Puritans of the day; and, as it is much desired, should any person know of its whereabouts, I should feel much obliged by a note of it. R. _Epistola Luciferi, &c._--Nicolas Oresmius, or d'Oresme, bishop of Lisieux, who died in 1382, wrote _Epistola Luciferi ad prælatos Ecclesiæ_, afterwards printed, Magd. 1549, 8vo., and in Wolf's _Lect. Memor._, vol. i. p. 654. So far Fabricius. Who was Lucifer? I mean, was he the potentate who goes by the opposite name of the Prince of Darkness? And what is the tenor of his letter? The bishop was a quiet man, of orthodox fame, and tutor to a king of France. M. _Cambrian Literature._--Being a collector of works on Druidical remains and Cambrian history, I shall feel greatly favoured if any of your numerous readers will answer me the following questions, viz.:-- 1st. The name of the first book or commentary _printed_ in any language abroad, _previous_ to the introduction of printing into England, actually written by a _Cambrian_? 2nd. The first book _printed_ in the English language, _actually written_ by a Cambrian then living? 3rd. The first and second books _printed_ in England in the _Welsh_ language? 4th. The first book printed in the Welsh language abroad? 5th. The first book printed in the Welsh language in Wales? 6th. The most _ancient author_ in MSS. and in print who mentions Stonehenge and Aubury; also the monument called Cromlêch?
