Ayloffe's published writings came later in life and were no great success with the general public. In 1751 he sent out proposals for printing by subscription the debates in Parliament before the Restoration in eight octavo volumes. Little favour was apparently extended to the scheme. Although in 1773 it was advertised that the first volumes would soon go to the press, none appears to have been published (cf. Rawlinson MSS. in the Bodleian, s. v. 'Ayloffe'). Also in 1751, Sir Joseph issued a prospectus for subscribers to a translation of
Diderot's and
D'Alembert's
Encyclopédie, with additional or expanded articles on subjects of English interest, but the first number, published on 11 June 1752, obtained scanty support and was severely handled in the ''Gentleman's Magazine'' (xxii. 46), so that the project was abandoned. Some years previously, Ayloffe had induced
Joshua Kirby, a well-known draughtsman of Ipswich, to prepare some engravings of the chief buildings and monuments in
Suffolk. Twelve of them were published with descriptive letterpress by Ayloffe in 1748. It was Ayloffe's intention to introduce Kirby's drawings into an elaborate history of the county upon which he was apparently engaged for the succeeding 15 years. In 1764 he had made such progress in collecting and arranging his materials that he issued a lengthy prospectus for publication of an exhaustive
Topographical and Historical Description of Suffolk, but sadly he again received too little encouragement to warrant him in pursuing the plan further. Subsequently, Ayloffe contributed several memoirs to
Archæologia, the journal of the Society of Antiquaries, which were highly valued at the time. On 25 February 1763 he "communicated" an interesting
Copy of a Proclamation (1563)
relating to Persons making Portraits of Queen Elizabeth (ii. 169–170). In 1773 and 1774 there appeared in
Archæologia (iii. 185–229,2.39-272, 376–413) three papers by him, describing: • A picture at Windsor of the famous interview in 1520 between Henry VIII and Francis I • Four pictures at Cowdray near Midhurst, the property of Lord Montague, illustrating Henry VIII's wars in France in the latter part of his reign • The opening of the tomb of Edward I at Westminster in 1774, an exhumation that Ayloffe with Daines Barrington superintended. Another paper prepared for the Society of Antiquaries,
On Five Monuments in Westminster Abbey, was published separately, with engravings, in 1780. An account of the chapel on London Bridge, by Ayloffe, was published with a drawing by
George Vertue in 1777. In 1772 Ayloffe published a work for which he is still known to history students:
Calendars of the Ancient Charters, and of the Welsh and Scottish Rolls, Now Remaining in the Tower of London... to Which are Added Memoranda Concerning the Affairs of Ireland [and an] Account of the State of The Public Records [etc.]. London, 1774. This, with an introduction attributed mainly to
Thomas Astle, traces the history and neglect of the Public Records. In a long introduction, Ayloffe pressed for scholarly research among the state papers. The book was begun by the Rev.
Philip Morant, who had been employed at the State Paper Office, and was published anonymously, but a reissue in 1774 had Ayloffe's name on the title-page. Ayloffe also revised for the press new editions of
John Leland's
Collectanea (1771) and of the
Liber Niger Scaccarii (1771), and added valuable appendices of original illustrative documents. He saw through the press
John Thorpe's
Registrum Roffense, which was published in 1769 by the compiler's son. Ayloffe's
Collections relative to Saxon and English Laws and Antiquities remain in manuscript at the
British Library (Add MS 9051). The whereabouts of his other manuscript collections have not been traced, numerous as they clearly were and stated by contemporaries to have been invaluable in relation to the
abbey and
city of Westminster. His library was sold by Leigh and Sotheby soon after his death. ==Notes==
