Raquia (רָקִיעַ) is the firmament—the solid, crystalline expanse created on the second day of Genesis to divide the primordial waters. In Hebrew, the root רקע (rqʿ) conveys the idea of stamping, spreading, or beating out a metal plate, suggesting a hammered, translucent dome that holds back the upper cosmic ocean. This is not a void but a structured barrier, often envisioned as a sapphire-like platform or a sheet of ice, through which the stars are fixed as living lights.

Position on the Tree of Life

Raquia occupies the eighth position on the Tree of Life, corresponding to the Sephirah Hod (Splendor) on the Pillar of Severity. As the heaven of Assiah (the material world), it is the lowest of the seven heavens that still retains a direct link to the divine order. In the scale of 777, it follows the more turbulent Shechaqim (Netzach) and precedes the sublunary realms of Tebel and Vilon. This placement aligns with Hod's function as the sphere of intellect, communication, and the formal structures that give shape to raw force.

Astrological and planetary correspondence

In the system of 777, Raquia is assigned to the planet Mercury (Kokab), which rules Hod. Mercury’s swift, analytical, and adaptive nature mirrors the firmament’s role as a boundary that both separates and mediates—a crystalline membrane through which divine light passes into the lower worlds. The fixed stars within Raquia are said to be the letters of the cosmic alphabet, written in fire upon the sapphire floor.

Historical context

The concept of Raquia originates in the Priestly source of the Torah (Genesis 1:6-8), where Elohim calls the firmament “Shamaim” (heavens). By the Second Temple period, Jewish apocalyptic literature—particularly 1 Enoch and the Testament of Levi—had elaborated a seven-tiered heaven, with Raquia as the fifth. In the 3 Enoch (Sefer Hekhalot), Raquia is the realm where the angelic princes of the nations stand in judgment, and where the celestial curtains (pargod) are woven from divine names. The Zohar later identifies Raquia with the “treasury of life” and the place where the souls of the unborn await descent.

In the Hermetic Qabalah of the Renaissance, Raquia was syncretized with the Ptolemaic sphere of Mercury. The 17th-century occultist Athanasius Kircher, in his Oedipus Aegyptiacus, depicted Raquia as a crystalline sphere engraved with the 22 Hebrew letters, each a channel of divine emanation. The 777 table inherits this tradition, placing Raquia at the Hod step of Assiah, where the intellectual architecture of the universe is fixed into a firmament of law and number.

In Liber 777

In the table of 777, Raquia appears as the Heaven of Assiah at the Hod step (scale step 8). It is the fifth heaven in the descending series from Araboth (Keter) to Vilon (Malkuth), and its correspondences include the angelic order of the Hashmallim (the “speaking flames”) and the divine name Elohim Tzabaoth. As the firmament of Mercury, it governs the sphere of rational structure, magical language, and the crystalline clarity of the sephirotic system made manifest in the physical world.
