_Anthony Warton._--Who was Anthony Warton, minister of the word at Breamore, in Hampshire, and author of _Refinement of Zion_, London, 1657? Another Anthony Warton was matriculated at Magdalen College, Oxford, 2nd Nov., 1665, at sixteen, as son of Francis Warton, of Breamore, Hants, plebeian. He remained clerk till 1671; chaplain from 1671 to 1674; instituted vicar of Godalming, Surrey, in 1682; obiit 15th March, 1714-15. He was father of Thomas Warton, Demy and Fellow of Magdalen College, vicar of Basingstoke, Hants, and of Cobham, Surrey, Professor of Poetry in the University of Oxford, 1718-28; who was father of the more celebrated Thomas Warton, Fellow of Trinity College, Oxford, and of Joseph Warton, Head Master of Winchester School. Manning says (_History of Surrey_, vol. i. p. 648.) that Anthony Warton, vicar of Breamore, Hants, was younger brother of Michael Warton, Esq., of Beverley, but originally of Warton Hall in Lancashire. Both Wood and Manning seem to have confounded the first Anthony with the clerk, &c. of Magdalen. Was the former brother of Francis? MAGDALENENSIS. _Cardinal's Hat._--O'Halloran mentions the cardinal's hat--"birede"--"biretrum"--as the hat anciently worn by the Irish doctors. What is its history? J. SANSOM. _Maps of London._--I should be grateful to any of your correspondents who could inform me whether there are any maps of London before that of Aggas? what they are? and where they are to be found? The date of Aggas's map is supposed to be about 1560, and must have been after 1548, as the site of Essex House in the Strand is there called "Paget Place." There is a MS. map by Anthony Van Den Wyngerde in the Sutherland Collection in the Bodleian, the date of which would be about 1559. EDWARD FOSS. _Griffith of Penrhyn._--Can any of your correspondents refer me to a good pedigree of GRIFFITH OF PENRHYN AND CARNARVON? WILLIAM D'OYLY BAYLEY. Coatham, near Redcar. _The Mariner's Compass._--What is the origin of the _fleur-de-lis_ with which the northern radius of the compass-card is always ornamented? NAUTILUS. _Pontefract on the Thames._--Permit me to ask, through the medium of your useful publication, where Pontefract _on the Thames_ was situate in {57} the fourteenth century? Several documents of Edw. II. are dated from Shene (Richmond); in 1318, one from Mortelak; in 1322, one from Istelworth; and several are dated _Pountfrcyt_, or _Pontem fractum super Thamis_. (See Rymer's _Foedera_). It is very clear that this Pountfrcyt on the Thames must have been at no great distance from Shene, Mortlake, and Isleworth, also upon the Thames; and this is further corroborated by the dates following, from the places alluded to, so closely. <pointing hand> N.
