According to Mortimer Luddington Menpes (1860-1938) this was a 'Wash drawing of St Paul's / Study for an etched plate', but no such etched plate has survived. 1
It was probably drawn using a quill pen, and then developed with the feathered end of the quill, using mostly water. In some cases the wash may have been applied first, and pen line drawn through it, the result being that the ink spreads out on each side of the line. 2
