Obscura Paintings

 are five 15th century works of Black alchemic magic by Pieter Van Eckhardt. The painting each contained a piece of Sanglyph, to keep it safe. After Eckhardt's imprisonment, the painting were overpainted with religious imagery, and hidden by Brother Obscura of Lux Veritatis all over Europe. Brother Obscura also created copies of those paintings, called Obscura Engravings, where he hid the location of the paintings.

In 2003 Mathias Vasiley obtained all Obscura Engravings, that led to the discovery of those paintings.
