Celtic Mythology
The Druids, the tree calendar, and the otherworld
Overview
Celtic spirituality was an oral tradition of extraordinary depth — the Druids spent 20 years in training and encoded cosmic wisdom in the patterns of nature. The Celtic tree zodiac (Ogham calendar) assigns personality archetypes to the 13 lunar months of the year. The Celts saw time as cyclical, the veil between worlds as thin, and nature as sacred text.
Cosmological Worldview
Celtic cosmology revolved around the Otherworld (Tír na nÓg) — a realm parallel to the mortal world, accessible through mounds (sídhe), sacred springs, and liminal times like Samhain. The year turned on four great fire festivals: Imbolc, Beltane, Lughnasadh, and Samhain — which survive as the modern Wheel of the Year.
