Skag Rock, Pembrokeshire

Skag Rock, Pembrokeshire, painted in 1879 and held by the National Trust, documents a specific geological feature on the Pembrokeshire coast of south-west Wales. Pembrokeshire's coastline is among the most geologically diverse in Britain, where ancient Pre-Cambrian rock meets the sea in dramatic formations of a kind quite different from the sedimentary limestone and chalk of southern England. Brett was exploring the Welsh coast from his yacht during the late 1870s, extending his British coastal survey westward after establishing his Dorset and Devon subjects. The specific naming of an individual rock formation — Skag Rock — is characteristic of Brett's documentary approach, treating each painting as a geological record of a specific, locatable feature.

Pembrokeshire's ancient igneous and metamorphic rock has a darker, more complex coloration than Brett's English subjects, and his palette responds accordingly. The Atlantic exposure of the Pembrokeshire coast produces more vigorous wave action than the Channel, requiring a different approach to sea surface rendering. The compositional format maintains his mature low-horizon approach.
