The tree of knowledge; a startling scientific study of the original sin, and the sin of the angels, with a history of spiritism in all ages
A late nineteenth-century American spiritualism treatise by Russell Kelso Carter, published in San Francisco in 1894 by O.H. Elliott, aimed at readers interested in religious and occult speculation about original sin. Its pictures are monochrome halftone-style engravings in red and purple tones, showing a robed figure on a dark cliff, a winged serpent-tailed creature with a small figure, a crowd of struggling bodies, and a shadowy figure beside a fallen beast; a designer could take the tinted duotone palettes and the dramatic, cave-like compositions as reference for moody, sepulchral layouts.
