Well preserved and consigned fresh to the market from a local source, they show the craggy coastline of the island of Madeira where they were painted in 1849.

Companion works, Chapel in the Rock and Sartinha and Loo Rock, bettered their £200-300 guide to sell to an Irish buyer at £1550.

The same buyer also secured the third watercolour, a 13 x 9½in (33 x 24cm) work of a house situated on a rock in Funchal. It made £850 against a £100-200 estimate.

The highest price recorded for a Madeira landscape by Dillon was fetched at Bonhams in 2012 when a watercolour of the chapel in Machico, also 1849, sold for £2800.

Dillon travelled to many parts of the world and is considered one of the youngest members of the great generation of British topographical painters that flourished in the first half of the 19th century.
