A pencil and wash sketch of a ruined castle by moonlight, with houses and figures in the foreground; one of three works which together consistute a lesson in painting for Queen Victoria, accompanied by a detailed explanation of the three stages in painting such a watercolour written by the artist.

This watercolour, the third stage in Leitch's visual painting lesson, shows further colour added and tones strengthened to stages one (RCIN 919718) and two (919719) of the lesson.

Leitch taught Queen Victoria between 1846 and 1865, as well as other members of the royal family. The Queen found Leitch an excellent drawing master, and on his death in 1888 wrote in her journal of her sadness at the passing of 'dear old Mr Leitch, my kind drawing Master, such an excellent artist, known to me for so many years, connected with happy and sad times, & with Scotland'.
