Considered a Pre-Raphaelite work, Dyce employs a mode of heightened realism and intricate detail to create a powerful landscape.
Standing separately the foreground are Dyce's son with a spade looking out to sea, his wife, and her two sisters, collecting shells and fossils on the beach.
The beach was frequented by Charles Darwin and his family, and On the Origin of Species was published in 1859, while Dyce was working on the painting.
The painting can be seen as an allegory of time and space, geology and astronomy, family and history, with science meeting Christianity on the beach: Pegwell Bay was reputedly the place where St Augustine landed in 597, on his mission to bring Christianity to the British Isles (and also where Hengist and Horsa arrived in the 5th century).
The comet may be an echo of the Star of Bethlehem from the biblical nativity story, but could also be a reference to the science of astronomy and the place of humans in the universe.
