This time of year the dose of sunlight rises each day toward the long fuse of solstice. In the Celtic tree zodiac, the period from May 13th to June 9th is represented by Hawthorn—or huath as it was called in old Irish. In the most general sense, this time of year, also known as the Hawthorn moon, is associated with fertility—and also the rising of light, suggestive of male sexuality. “Ne'er cast a cloot til Mey's oot," it was said. Don’t take off your cloots (clothes) until the May blossoms (hawthorn) appear.
