Theogonie from the Sources of Classical, Hebrew and Christian Antiquity

"Theogonie" is one of Feuerback's core works published in 1857 that explores the origins and nature of religious belief, particularly in relation to ancient Greek mythology. It is titled after The epic poem by Hesiod of the same name. In this work, Feuerbach argues that the gods of Greek mythology are projections of human consciousness and that the true essence of religion can only be understood by examining the human mind and its relationship to the natural world. He extends this critique of religion to the modern day and uses it to argue against Hegelianism. Nietzsche copies this critique early in his career, making the same argument that religion merely is a defense mechanism, and morality merely a tool for the weak to restrict the strong.

Schopenhauer and Nietzsche both took their satirical criticism about religion from Feuerbach, and every aspect of Marxism can be found here in Marx's favorite Philosopher. Feuerbach is a critical figure in the development of not merely Marxism, but Materialistic Humanism in general. Feuerbach is critical to understanding Marx.
