Another stationer, George Chastelain, is first mentioned in the imprint of a grammar printed by Pynson about 1499, “Here endeth the Accidence made at the instance of George Chastelayn and John Bars.” There is no indication where he was then at work, but in 1502 he was admitted as a servant to the liberties of the University. About 1507 Pynson printed for him an edition of the _Principia_ of Peregrinus de Lugo, an extremely rare book, of which, however, there is a copy in the University Library. In this his address is given as the sign of St John Evangelist in the street of St Mary the Virgin. He was a bookbinder as well as a stationer, and in the registers of Magdalen College frequent mention is made of him between 1507 and 1513 as binding books for their library. He died in 1513, and his will was administered by Mr. Wutton and Henry Jacobi, a stationer. An inventory of his goods was made by Howberch, a University stationer, and Richard Pate, and the value returned at £24. Some time between 1512 and 1514 a stationer named Henry Jacobi migrated from London to Oxford. From 1506 to 1508 he had been in partnership with another bookseller named Joyce Pelgrim, and assisted by a wealthy London merchant named Bretton they issued several books together. Between 1509 and 1512 Jacobi published books alone, though he appears to have still been helped by Bretton. One book is known printed for Jacobi at Oxford, an edition of the _Formalitates_ of Antonius Sirectus. An imperfect title-page and a few leaves were found by Proctor in the binding of a book in New College Library, and shortly afterwards a copy of the book, wanting a greater part of the title, was identified in the British Museum. It is a quarto of twenty-two leaves, and was printed in London by W. de Worde. On the title-page is the very finely engraved device of Jacobi, probably newly cut, and found in no other of his books, though it was used again in a mutilated state by his successor; and below the device an imprint stating that the book was to be sold in the University of Oxford at the sign of the Trinity, by Henry Jacobi, a London bookseller. His shop in London in St Paul’s Churchyard had also the sign of the Trinity. Jacobi made his will on September 8, 1514, and died shortly after. On November 9 his wife renounced her executorship, and administration was granted to William Bretton, the rich merchant who had assisted him throughout his career. On December 11 administration of the effects of Jacobi was granted at Oxford also to Bretton through his agent, Joyce Pelgrim, Jacobi’s former partner.
