Ever since the publication of Parentalia in 1750 it has been taken for granted that all the ‘fifty-one parochial churches of the City of London’ listed there by Christopher Wren, junior, were indeed ‘erected according to the Designs, and under the Care and Conduct, of Sir Christopher Wren’. That Wren could not personally have designed every detail of so many churches has long been recognized, and it is well known that in most cases the fittings, and in some even the architectural details, were designed by the craftsmen employed. Even if Wren ‘originated the design of every church’, ‘in many cases the working out and supervision was done by somebody else’ — generally by Robert Hooke or Edward Woodroffe, or after Woodroffe’s death in 1675, by John Oliver, Wren’s deputy as Surveyor of St Paul’s Cathedral. Of the many surviving drawings, relatively few are in Wren’s own hand. Some are clearly by Hooke, whose characteristic draughtsmanship is fairly easy to recognize, some no doubt are by Woodroffe, and some must be by the draughtsmen named in Wren’s accounts for rebuilding the churches: first William Walgrave, who in or about 1673 was paid £2 10s. ‘for taking the ground platts of 12 churches yet unbuilt’, then Henry Hunt, who received £6 10s. for thirteen similar plans in 1676/77, and finally Thomas Lane, who between 1676/77 and 1682 was regularly paid ‘for coppying the Designes of severall Churches’, then ‘for drawing the designes for severall Churches’, and finally for ‘drawing and making designes for severall Churches’.
