Example of Dyad Tree Ogam

F-D = Fad - dimensions of the globe, T-T = Tuath -

North, B = bi - set, Q-N = ceann - at the, T = ta -top,

D-S = deas - south, F-B = fo - below.

North is set at the top, south below.

Evidently influence by Norse fellow settlers in the west, the ancient

American Irish immigrant combined the mystical concept of the

world-tree Yggdrasil with a scientific understanding that the

earth is in fact a globe (see Fell 1982).
