[1] Attending Plymouth Grammar School, he came under the influence of its schoolmaster, John Bidlake, who encouraged the young Prout and Benjamin Robert Haydon in their artistic apprenticeship.
They spent whole summer days drawing the quiet cottages, rustic bridges and romantic watermills of the beautiful valleys of Devon.
Happening time to make his first visit to the Continent, and to study the quaint streets and market-places of continental cities, he suddenly found himself in a new and enchanting province of art.
To Prout, therefore, goes credit for the creation of the essential characteristics lacking in earlier art, in particular "that feeling which results from the influence, among the noble lines of architecture, of the rent and the rust, the fissure, the lichen, and the weed, and from the writings upon the pages of ancient walls of the confused hieroglyphics of human history".
At the time of his death there was hardly a place in France, Germany, Italy (especially Venice) or the Netherlands where his face had not been seen searching for antique gables and sculptured pieces of stone.
He died after a stroke at his home, 5 De Crespigny Terrace, Denmark Hill, London and was buried at West Norwood Cemetery.
The collection was sold at auction in 2010, and much was acquired by Plymouth City Museum & Art Gallery, adding to its existing holdings of his work.
