John Ruskin (1819-1900) is healthier recognized for his paintings as an artwork critic and social critic, yet is remembered as an writer, poet and artist to boot. Ruskin's essays on paintings and structure have been super influential within the Victorian and Edwardian eras. Ruskin's diversity was once huge. He wrote over 250 works which all started from artwork background, yet increased to hide themes ranging over technology, geology, ornithology, literary feedback, the environmental results of toxins, and mythology.
