There is an evident connection between such a study of light and shade as the ‘Interior of a Cottage’ (406 National Gallery) and at least two of the exhibits in the exhibition of 1797. One of these, the ‘Moonlight, a study at Millbank,’ was probably Turner’s first exhibited oil painting; the other, ‘Transept of Ewenny Priory, Glamorganshire,’ I am inclined to regard as the first drawing in which the budding genius of the young artist was authoritatively announced. It is impossible to be sure whether the direction of Turner’s attention to the subtler problems of light and shade led him to turn to oil painting as a more suitable medium for the expression of such effects, or whether his resolution to explore the resources of the more complex medium had the effect of directing his attention to the expressional qualities of light and shade. The ‘Millbank’ bears on its face the evidence of Dutch influence (Van der Neer, Van Goyen, etc.) as well as of inexperience of the technical requirements of the new medium. This inexperience renders the work [Illustration: _PLATE IX_ INTERIOR OF RIPON CATHEDRAL: NORTH TRANSEPT PENCIL. 1797] insignificant with regard to the development of the artist’s personality, but the bent of his mind towards the mystery and expressiveness of darkness is notable.
