(P.), a good painter of sea-pieces, was born in Jersey; and certainly (says Mr Walpole), from his circumstances or the views of his family he had little reason to expect the fame he afterwards acquired, having received his first rudiments of drawing from a sign and house painter on London-bridge. But when nature gives real talents they break forth in the home-taught school. The shallow waves that rolled under his window taught young Monamy what his master could not teach him, and fitted him to imitate the turbulence of the ocean. In painter's hall is a large piece by him, painted in 1726. He died at his house in Westminster the beginning of 1749.
