Of This Men Shall Know Nothing (German: Von diesem wissen Männer nichts) is oil on canvas painting by a German painter, sculptor, graphic artist, and poet Max Ernst.
It is created in a Surrealism style by use of symbolic painting genre during First French period.
[1] The painting shares several features with Silberer's diagram: its landscape setting and low horizon; the gradation of the sky from light at the bottom to dark at the top; and the inclusion of the Sun and the Moon.
Ernst replaced the cube of Primal Matter with a pile of entrails.
[2] Elsewhere Ernst also employed alchemical motifs, such as in this painting of the sexual conjunction of Sun and Moon.
