Elias Mollineaux Bancroft was a British painter active in the late 19th and early 20th centuries. Beyond that, I can find little in the way of background or biographical information.
Though he also took on other subjects, Bancroft apparently had a fascination with depicting walls and buildings made of stone or block. These he approached with a nicely visceral feeling of texture and weight.
I believe — as is often the case with images of artworks on the web — that some of the images of his work that you will encounter have been artificially brightened and raised in chroma by someone along the way in an attempt to make them “prettier”. In my example images above, I’ve taken the liberty of adjusting a couple of them to my best guess of their original appearance.
