These five profound lectures look at the cosmic
forces behind the four great festivals of the year,
providing a wealth of material for fruitful thought
and meditation. Steiner presents great imaginative
pictures that unite the heavens and the Earth through
a portrayal of the activities of the archangels Michael,
Gabriel, Raphael, and Uriel.

In the course of the lectures, Rudolf Steiner offers
spiritual insight into subjects that include the alchemical
processes of sulfur, mercury, and salt in the cosmos;
the realms of humankind and plants; spiritual 
ombustion processes; crystals; clouds and meteors;
the movements of elemental beings in nature; and the
conflicting efforts of Lucifer and Ahriman
he two great adversaries divert Earth from its true purpose.

The Four Seasons and the Archangels includes five
color plates of Rudolf Steiner blackboard drawings
made during the lectures.
