Seventy is the isopsephic value of Omicron (Ο, ο), the fifteenth letter of the Greek alphabet. Its name, o mikron (ὂ μικρόν), means "small O," distinguishing it from Omega (Ω, ω), the "great O." In the Greek numeral system, Omicron represents 70, a value it retains in the Qabalistic correspondences of Liber 777.

Position on the Tree of Life

Omicron corresponds to the 26th Path on the Tree of Life, the Path of Peh (פ), which connects Hod (Splendor) to Netzach (Victory). This Path is associated with the astrological sphere of Mars, and its number 70 reflects the martial, active, and analytical energies of this channel.

Astrological and planetary correspondence

Through its association with the Path of Peh, the number 70 is linked to the planet Mars. This connection imbues 70 with qualities of force, courage, and sharpness—attributes that align with the letter Omicron's shape (a circle) and its phonetic value as a short, open vowel.

Historical context

The isopsephic value of Omicron as 70 is a foundational element of Greek numerology and Qabalah. In the Hellenistic period, isopsephy (the practice of summing letter values) was used for magical and divinatory purposes. For example, the Greek word Σοφία (Sophia, "Wisdom") totals 781, but its component letters include Omicron (70) as a key element. In the Chaldean Oracles and later Hermetic texts, the number 70 appears in contexts of completion and cycles—such as the 70 years of a generation or the 70 elders of Israel—though its primary Qabalistic use is as the value of Omicron.

In Liber 777, the number 70 appears in the column "Numeration of Greek Alphabet" at the 26th step, corresponding to the Path of Peh. This placement reinforces the link between the Greek letter Omicron and the Hebrew letter Peh, both of which share the value 80 in their respective systems (Peh = 80; Omicron = 70). The discrepancy of 10 reflects the different numerical traditions, but the symbolic resonance remains: Omicron, as the "small O," is the vowel of the mouth (Peh means "mouth" in Hebrew), connecting speech, breath, and the martial force of Mars.

In Liber 777

At the 26th step (Path 26), the number 70 is the value assigned to the Greek alphabet in the column "Numeration of Greek Alphabet." It stands as the isopsephic equivalent of Omicron, linking the Greek letter to the Hebrew Peh and the Mars-ruled Path of the Tree of Life.
