Tree letter memory
An early Gaelic alphabet once harnessed the means to remember sacred beliefs, stories, medicine and time through its tree letters.
Thirteen consonants follow a sidereal rhythm for the thirteen lunar periods in a year, beginning with 'B' soon after the winter solstice
Five vowels follow a solar (sun-wise) direction tracking solstice and equinox points, beginning with 'A' at winter solstice.
Poems are by Aonghas MacNeacail, sound by Rob MacNeacail, images by Simon Fraser and sculpture by Helen Denerley. See more about the calendar, or simply begin with B (beithe/ birch) to start the lunar year
