Distinguished and influential British architect (1632–1723) who played a leading role in the rebuilding of London following the devastating Great Fire of 1666, and whose St. Paul’s Cathedral takes a place among the greatest designs in the history of architecture. Scarce manuscript DS, signed “Chr. Wren,” one page both sides, 9.25 x 14.75, April 12, 1700. A page from the “Abstract of the Expense of Provisions … for the month of March 1699” kept by Ralph Cooke, under-treasurer of the Royal Hospital at Chelsea, which was designed by Wren and completed in 1692. Cooke details payments to various named tradespeople, including a butcher, baker, brewer, cheese-monger, whitster [a “bleacher,” evidently of laundry], tallow chandler, lampman, and steward. Wren, along with two other trustees of the hospital, signs his approval at the center right of the first page. A hint of mild toning, very faint scattered soiling, and light creases to upper left blank area, otherwise crisp, bright, fine condition. A most appealing example of an uncommonly encountered autograph! LOA John Reznikoff/PSA/DNA and R&R COA.
