Celtic Ogham — tree-letter body correspondences

Modern neo-pagan Ogham tables commonly place Beith, the birch letter, with the lungs and the act of purification through breath. The chest anchor is an editorial focus for that symbolic association, not a medieval anatomical prescription.

Luis is the rowan letter and is commonly given protective force in modern neo-pagan practice, with the nerves as its body correspondence. It is placed on the upper neural axis as a symbolic projection; the manuscript lists do not establish this organ assignment.

Nion, associated with ash, is often linked in modern tables to the spine and the vertical world-linking axis. The front-view midline point makes the axis visible even though the physical spine lies posteriorly, so this is a deliberate projection convention.

Fearn, the alder letter, is mapped by the selected modern school to the shoulders and their supporting girdle. A right-side anchor (x < 0.5) keeps the paired-region convention visible while the letter itself is not anatomically right-sided.

Saille is the willow letter and is commonly associated with the eyes in modern neo-pagan body tables. The point sits at the anatomical-right eye region to show the bilateral visual focus without implying a one-sided doctrine.

Huath, the hawthorn letter, is assigned to the teeth in the selected modern correspondence school, fitting hawthorn's defensive and boundary symbolism. The mouth point is a compact front-view marker for the dental region, not a claim that medieval Ogham texts taught dental medicine.

Duir, oak, is the modern school’s clearest skeletal correspondence: bones, endurance, and strength. Because bones are distributed through the body, the trunk point is an intentionally broad representative anchor with high uncertainty.

Tinne, the holly letter, is mapped to joints in the selected modern body table, emphasizing firm articulation and resilience. The lateral trunk anchor represents a distributed set of joints rather than one anatomical joint.

Coll, hazel, is commonly linked to the brain, memory, and wisdom in modern neo-pagan Ogham teaching. The cranial point is a symbolic focus for cognition, not evidence that the medieval Ogham tracts divided the brain by letters.

Quert, usually rendered as the apple letter in modern tree alphabets, is associated with the heart and the centre of affection. The midline chest anchor presents the familiar modern body symbol while keeping its non-canonical status explicit.

Muin, linked with the vine, is assigned to the neck in the selected modern table, where binding and flow meet voice and expression. The point marks the cervical-throat transition as a symbolic region rather than a physiological claim.

Gort, the ivy letter, is mapped to skin in the chosen modern school because ivy suggests a persistent outer covering and boundary. The slightly left-of-midline chest point is only a representative surface marker; skin is distributed across the whole body.

nGéadal, commonly associated with reed in modern tree-letter lists, is placed at the throat and voice passage. The point is a front-view attention aid for the laryngeal region, not a claim of textual anatomy in the Auraicept.

Straif, rendered as blackthorn, is assigned to the glands in some modern Ogham anatomy tables, where hidden regulation mirrors the tree's guarded symbolism. Because this is a particularly variable modern attribution, the upper-abdominal anchor is broad and its uncertainty is high.

Ruis, associated with elder, is mapped to blood and circulating vitality in the selected modern body-correspondence school. Blood has no single surface locus, so the lower-trunk point is an intentionally diffuse visual anchor rather than an anatomical localisation.
