Matthijs Bril was a crucial pioneering figure within the tidal wave of artists from the Netherlands who travelled to Rome in the later 16th and early 17th centuries.  Between his arrival in Rome around 1574 and his premature death in 1583, Bril executed a series of ground-breaking drawings of Roman views and antiquities that were extremely influential in the development of landscape in Rome at this time, a story in which Bril's younger brother Paul subsequently played a vital role.  Nine drawings from this series survive, eight of them in the Louvre, the other in a private collection.¹  In comparison with those drawings, this panoramic view, which may once have constituted a double-page spread in a sketchbook, is strikingly spontaneous, but the details of the handling and the approach to perspective all argue strongly for the attribution to Matthijs Bril.
