The auction house Gorringe's revealed that appraisers spotted the painting in the Lewes home of a woman that had recently passed away.

The painting is titled 'Venice, The Dogana from the Bacino di San Marco' and is believed to date from the 18th century. It is expected to sell for £150,000 when it is auctioned next month.

The auction house said that the former owner of the painting was aware of the artist's identity but had decided not to sell the artwork.

Philip Taylor, managing partner at Gorringe's, said: "Bearing in mind larger paintings by the artist sell for millions, this is an opportunity for a collector to buy at a relatively affordable price.

"We are expecting great interest for a work by a celebrated artist that is fresh to the market after 100 years."
