The tenth lecture of the Gnostic Esoteric Astrology course explains the zodiacal sign of Capricorn (Dec 22 - Jan 19).

Quoted from the lecture:

"This beautiful zodiacal sign, Capricorn, house of Saturn, sign of Earth, relates to death. In the physical body it governs the knees.  The goat, which is a symbol of Capricorn, reminds us of the god Pan in the Greek and Roman mythology."
