Title: “Zoso” Sigil

Author: freakofnurture (derived source); unknown (creator of original)

Source: Derived from:  Zoso.svg. Likely from a sigil for Saturn from page 51 of an 1850 reprint of a 1521 French book Dragon Rouge and Poulet Noire (The Red Dragon and The Black Hen); also seen on page 31 of Frinellan’s 1844 book Le Triple Vocabulaire Infernal Manuel du Demonomane. A variation of the symbol also appears in Jerome Cardan‘s 1557 book De rerum varietate (page 789 of this 1580 reprint). Page’s original symbol was used in Led Zeppelin IV.

Date Created: 26 September 2010 (cropped from source); original likely from 1521 or earlier
