Thor is the Norse god of thunder, storms, and strength. His very name, from Old Norse Þórr, is the word for 'thunder,' cognate with the Germanic Donar and the Celtic Taranis. He is the son of Odin and the Earth goddess Jörð, and is married to the golden-haired Sif. His realm is Þrúðheimr, his home Bilskirnir.

Position on the Tree of Life

Thor appears in Liber 777 at the junction of the Thirty-third row, corresponding to Geburah on the Tree of Life (scale step 5). Geburah is the Sephirah of severity, strength, and judgment—the sphere of Mars, of the purging fire, of the strict law that breaks what is corrupt. Thor's hammer, Mjölnir, is not merely a weapon of destruction but an instrument of cosmic enforcement: it shatters the skulls of the jötnar (chaos-giants) who threaten the ordered world of gods and men. The qabalistic correspondence is exact: Geburah's force is a combative, dynamic severity, and Thor is its most direct mythological avatar.

Astrological and planetary correspondence

In the Lesser Key of Solomon and medieval astrological magic, Thor is not indexed directly. However, in the system of Liber 777, his position at Geburah aligns him with the sphere of Mars. His attributes—iron gauntlets, the Megingjörð (belt of strength), a red beard, a chariot drawn by the goats Tanngrisnir and Tanngnjóstr—all reflect the Martian temperament: impulsive, protective, fiercely destructive against obstruction. The hammer is the elemental weapon of Mars in the Western magical tradition.

Historical context

The oldest surviving sources for the figure of Thor are the Poetic Edda (13th century, but preserving older oral traditions) and the Prose Edda of Snorri Sturluson (c. 1220). In the poem Þrymskviða, Thor is tricked into dressing as a bride to reclaim his stolen hammer, revealing his volatile temper and brute-force cunning. He is invoked in dozens of Viking-age runestones and amulets, most famously the Kvinneby amulet and the Ribe skull fragment, where his name is called for protection against 'þurs' (evil spirits). The hammer was a common symbol carved on pagan graves as a ward against chaos.

Thor was the most popular god among the common people of the Viking world—far more widely revered than Odin—because his sphere was direct: weather, crops, safety from giants, and the sanctity of the oath sworn on the hammer-ring. Adam of Bremen (c. 1075) records that in the Temple at Uppsala, Thor occupied the central and highest throne, flanked by Odin and Freyr. The day of the week Thursday (Old Norse Þórsdagr, English Thunresdæg) preserves his name in the Germanic calendar.

In the Gylfaginning section of the Prose Edda, Thor is prophesied to die at Ragnarök after killing the Midgard Serpent—a battle that will shatter the earth. This is the tragedy of Geburah: the enforcer of order who must finally break the enemy that he himself has contained, and in so doing, be destroyed.

Place in Liber 777

In the table of correspondences, Thor appears not in isolation but as the manifest form of severity in the system of thirty-two paths and ten Sephiroth. His name stands in a cell that aligns him with the sephirotic formula of Mars, the number 5, and the ritual color of red. He is the militant edge of the divine, the enforcer who is not subtle, not wise, but necessary: the hammer that makes the circle hold.
