Onycha (also spelled onycha or operculum) refers to the calcified operculum (trapdoor lid) of certain marine snails, particularly from the genus Strombus or related species. The term derives from Greek ὄνυξ (onyx, meaning 'nail' or 'claw'), reflecting the shell's hard, nail-like structure. In antiquity, onycha was burned as incense, valued for its sharp, salty, and slightly fishy aroma—a scent associated with the sea and the depths. It appears in early Jewish and Christian liturgical texts, notably in the Book of Exodus (30:34) as a component of the holy incense (ketoret), alongside stacte, frankincense, and galbanum. In the Qabalistic tradition, onycha is assigned to Binah (the third Sephirah, Understanding) and the planet Saturn. This correspondence emphasizes its qualities of structure, limitation, gravity, and the binding of form—the 'nail' that seals and secures. Onycha's marine origin also ties it to the element Water and the abyss, aligning with Binah's receptive, deep nature. Its use in incense blends for solemn rites, funerals, or meditative practices reflects a purpose of grounding, protection, and connection to ancestral or underworld realms.

Myrrh (from Hebrew מור mor, Arabic murr, meaning 'bitter') is the aromatic gum resin exuded from trees of the genus Commiphora, especially Commiphora myrrha and related species. Native to East Africa, Arabia, and the Indian subcontinent, myrrh has been traded since ancient times for its warm, balsamic, slightly bitter odor. It was a key ingredient in Egyptian embalming mixtures, Greek and Roman perfumes, and biblical incense. In Exodus 30:23, myrrh is listed as a primary component of the holy anointing oil, along with cinnamon, cassia, and calamus. In the Qabalistic system, myrrh corresponds to Binah (Understanding) and also to Geburah (Severity) and Mars, depending on context. Its bitterness and fiery nature align with Geburah's qualities of judgment, purification, and transformative power. Myrrh is often used in rites of protection, exorcism, and healing of spiritual wounds. Its association with death and rebirth—through embalming and its role in funerary incense—connects it to the sphere of Binah as the great receiver and transformer of souls. In alchemy, myrrh represents the principle of fixation and the 'bitter' stage of the Great Work, corresponding to the nigredo phase.

Position on the Tree of Life

Both Onycha and Myrrh appear at Path 23 (the 23rd step or path on the Tree of Life) within the column of Perfumes in Liber 777. Path 23 is the path connecting Hod (Splendor, eighth Sephirah) to Netzach (Victory, seventh Sephirah). This path is associated with the planet Mercury and the astrological sign Gemini, governing communication, duality, and the synthesis of opposites. However, the specific row for Perfumes at this step lists Onycha and Myrrh together, indicating their shared placement and complementary roles. In the broader schema, Path 23 is also linked to the 23rd Tarot Trump, 'The Fool' (or 'The Madman' in some decks), symbolizing innocence, spontaneity, and the beginning of a journey. The pairing of Onycha and Myrrh here suggests a balance between the binding, structural nature of Onycha (Saturn/Binah) and the transformative, purifying nature of Myrrh (Mars/Geburah). Together, they represent a gateway between the lower and upper spheres, mediating the flow of spiritual energy through form and change.

Astrological and Planetary Correspondence

In the Liber 777 table, Onycha is assigned to Binah (Understanding) and Saturn. Saturn's qualities of limitation, discipline, and the crystallization of form resonate with onycha's hard, shell-like structure and its use in binding and sealing rituals. Myrrh is also assigned to Binah, but additionally to Geburah (Severity) and Mars. Mars' fiery, active, and purifying nature aligns with myrrh's bitterness and its role in cleansing, protection, and transformative processes. The dual assignment reflects myrrh's complex character: it partakes of both the receptive depth of Binah and the assertive force of Geburah. In astrological terms, Saturn and Mars are opposing forces—one contracting, the other expanding—yet their conjunction in these resins suggests a synthesis of structure and energy, form and change.

Historical Context

Both substances have deep roots in ancient religious and medicinal practice.

Onycha appears in the biblical recipe for ketoret (holy incense) in Exodus 30:34, where it is called shecheleth (possibly a transliteration of the Semitic name). The Talmud and later Jewish commentaries describe onycha as the operculum of a marine snail, burned to produce a pungent odor that 'ascends like smoke from the sea'. In Christian tradition, onycha was used in early church incense, often combined with myrrh and frankincense. Its marine scent was thought to evoke the primordial waters and the deep, linking it to themes of creation and the abyss. In alchemy, onycha was sometimes classified among the 'sea resins' or 'marine incenses', valued for its fixative properties and its ability to bind other aromas.

Myrrh has an even broader historical footprint. It was one of the most prized trade goods of the ancient world, mentioned in Egyptian texts, the Bible, Greek and Roman sources, and Chinese materia medica. In Egypt, myrrh was used in embalming, as a perfume, and in temple rituals. The Ebers Papyrus (c. 1550 BCE) includes myrrh in remedies for wounds, inflammation, and spiritual ailments. In the Bible, myrrh appears as a gift of the Magi (Matthew 2:11), as a component of the anointing oil (Exodus 30:23), and as a symbol of suffering and bitterness (e.g., Psalm 69:21, 'they gave me gall to drink, and myrrh to eat'). In Greek and Roman culture, myrrh was burned at funerals, used in cosmetics, and employed as a disinfectant. In medieval Europe, myrrh was a key ingredient in incense for churches and in alchemical preparations. Its association with Mars and Geburah in Qabalah reflects its fiery, purifying nature—used in rites of exorcism, protection, and the transformation of negative energies.

Symbolic and Ritual Use

In the Qabalistic framework, both resins serve distinct symbolic functions:

• Onycha (Saturn/Binah) represents the principle of binding and sealing. Its hard, shell-like nature evokes the 'nail' that fixes, the limit that defines, and the structure that contains. In ritual, onycha is used to create boundaries, to anchor spiritual work in the material world, and to connect with ancestral or underworld forces. Its marine scent ties it to the element Water and the abyss, making it suitable for rites involving depth, mystery, and the subconscious.

• Myrrh (Mars/Geburah) represents the principle of transformation and purification. Its bitterness and heat signify the fire that burns away dross, the judgment that refines, and the pain that precedes rebirth. In ritual, myrrh is used for cleansing, protection, exorcism, and healing. It is often burned in times of crisis or transition, to sever old ties and open new paths. Its association with death and embalming also connects it to the sphere of Binah as the receiver of souls, making it a bridge between the living and the dead.

Together, onycha and myrrh at Path 23 embody a gateway between structure and change, between the fixed and the fluid. Their combined use in incense blends (e.g., the biblical ketoret) reflects a harmony of opposites: the binding nail and the bitter fire, the sea depth and the desert heat. In alchemical terms, this pairing corresponds to the coagula (fixation) and solve (dissolution) stages of the Great Work.

In Liber 777

At Path 23 (Perfumes row), the entry reads: Onycha, Myrrh. This concise listing indicates their shared placement and complementary roles within the Qabalistic system. No further attributes or distinctions are noted in the table itself, but the broader context of Liber 777 assigns each to specific Sephirotic and planetary correspondences as described above. The pairing here suggests a synthesis of the Saturnine and Martian principles, a union of depth and fire that mediates the flow of spiritual energy through the path of Hod to Netzach.

In practical ritual work, onycha and myrrh are often combined in incense formulas for protection, grounding, and transformation. Their aromas—one sharp and marine, the other warm and bitter—create a layered scent that evokes both the abyss and the forge. This blend is used in ceremonies of initiation, funerary rites, and meditative practices aimed at bridging the material and spiritual worlds.

Closing

Thus, Onycha and Myrrh stand as two distinct yet complementary resins within the Qabalistic tradition. Onycha, the 'nail of the sea', binds and seals; Myrrh, the 'bitter fire', purges and transforms. Together at Path 23, they represent the dynamic interplay of form and change, structure and dissolution—a gateway through which the soul may pass from the fixed to the free, from the depths to the heights.
