Ian Warrell has associated this composition with the ‘Little Liber’;1 the elemental, luminous image is comparable with Shields Lighthouse (Tate D25431; Turner Bequest CCLXIII 308), one of the canonical watercolours engraved for the series. See also Tate D25305 (Turner Bequest CCLXIII 183) and D40138 in the present subsection.
Loose pencil marks presumably indicate waves, although the sea is barely developed except where a vertical strip of colour has been lifted to indicate the path of the moon’s reflection. The washes of the sky have been extensively worked while wet with the colour lifted in small rounded patches, perhaps using the fingertips, to suggest a halo of light, fluffy clouds around the moon, intensifying its brightness.
