To meet all these expenses the King’s endowment was generous. The Deanery of St. Martin-le-Grand, the Priory of Luffield, various manors and advowsons formed substantial gifts, while a sum of more than five thousand pounds in money was made over for the purchase of other estates. In the Orde MS. there is the entry of a payment of thirty thousand pounds for the purchase of lands for the King’s new chapel, but it is not possible to verify the accuracy of what is only a transcript from the privy purse expenses of the King. The same manuscript records in seventeen different items the payment of £9,844 18s. 3d. to the Abbot of Westminster for the carrying on of the building between October 1st, 1502, and May 20th, 1505. A number of entries in the King’s Books of Payments (Treasury of Receipts) beginning in January, 1506, amount to more than £11,188, and so the total expenditure on the new building was certainly more than twenty-one thousand pounds. The last entry occurs on April 15th, 1509, about a week before the King died. It would appear to be a final payment for it refers to the _accomplishment and performing_ of the chapel, while no entries of payments occur in the succeeding book. It is unfortunate that it is not at present possible to do much more than note the cost of the chapel and the years occupied in the building, for the “reckonings” which were presented by Islip from time to time for the royal approval do not appear, though all probable sources have been searched. Islip would seem to have been the general supervisor of the works and responsible for the disbursement of the money, but the building itself was carried on under the direction of the royal workmen. One problem of the greatest interest remains unsolved, and that is the identity of the master-mason or architect who made the original design and plan of the chapel. Among the names suggested have been John Alcock, Bishop of Ely from 1486 to 1501; Sir Reginald Bray; Richard Fox, Bishop of Winchester from 1501 to 1528, and even the King himself. Mr. Lethaby[4] assumes that there can be no doubt that Robert Vertue, the senior royal mason, was the architect, but in the absence of evidence the matter must remain unsolved. It is to be noted that the only person mentioned in the directions as to the chapel given in the will of Henry VII. is the Prior of St. Bartholomew’s, Smithfield, who is described there as the master of the works of the said chapel. The reference is of course to Bolton who was Prior from 1505 to 1532 and whose work in his own church may still be seen. Stow refers to him as a great builder and in any discussion as to the identity of the architect his name must not be forgotten.
