Dyad Tree Ogam
When written vertically, dyad ogam forms as a tree-shaped figure where the left-handed branches carry the signs of the h-series (left-hand finger ogam), and the right-hand branches take the signs of the b-series (right-hand finger ogam). This style, evidently of great antiquity, appears on coinage of the Thracian Norse-Irish and is especially conspicuous in the Takhelne inscriptions of British Columbia. The upper diagram is taken from the Book of Ballymote and is identified to the left by the scribe in Middle Irish Script as "ogam dyad" (Fell 1982).
