John Knox was one of Scotland's most significant and original landscape painters. His family moved to Glasgow in 1799 and he may have trained with Alexander Nasmyth. As well as fairly conventional views of the Clyde valley and other picturesque sites, composed in the classical tradition, he produced some highly unusual and dramatic panoramas, taken from unusual viewpoints, such as the top of a mountain. Knox was also an influential teacher; Horatio McCulloch and Daniel McNee are both associated with the older artist.
