Millais / The Martyr of the Solway. The story behind this picture is tragic: Margaret Wilson, a member of the Free Church who refused to recognise the established Church of Scotland, condemned to death by drowning for her beliefs. The painting shows her chained to rocks on the Solway Firth where she and a friend were condemned to death by drowning in 1685. It is said that as the tide rose she defiantly quoted and sang from scripture, and witnesses described how her hair floated.
