One of several collaborative efforts in measuring and drawing buildings made with Thomas Hardwick whose related plan drawn to the same scale and dated 'June 1778' is in the RIBA Drawings Collection (SB60/11)

The great central hall (tepidarium) of the Baths of Diocletian was remodelled as the Church of Santa Maria degli Angeli to a design by Michelangelo, 1563-6 - the foundation stone laid in 1561 and building work finished by about 1590. From 1749, the church was enlarged and the orientation altered by Luigi Vanvitelli (1700-73).

Sir John Soane's collection includes some 30,000 architectural, design and topographical drawings which is a very important resource for scholars worldwide. His was the first architect’s collection to attempt to preserve the best in design for the architectural profession in the future, and it did so by assembling as exemplars surviving drawings by great Renaissance masters and by the leading architects in Britain in the 17th and 18th centuries and his near contemporaries such as Sir William Chambers, Robert Adam and George Dance the Younger. These drawings sit side by side with 9,000 drawings in Soane’s own hand or those of the pupils in his office, covering his early work as a student, his time in Italy and the drawings produced in the course of his architectural practice from 1780 until the 1830s.
