The Cailleach and Brigid

Ireland/Scotland Seasonal myth Winter Spring Cycle

The hag Cailleach shapes winter’s storms; Brigid brings spring’s thaw. At Imbolc, power shifts—Cailleach grows weary or turns to stone, Brigid’s flame and hearth revive the land—marking the turning of seasons.

Story beats

  1. 1) Cailleach, veiled hag, builds mountains and lashes the land with winter winds; she carries a hammer or staff to freeze the earth.
  2. 2) Brigid, radiant maiden, guards hearth, poetry, and smithing; her flame brings lambing season and green shoots.
  3. 3) On Imbolc (Feb 1–2), Cailleach gathers firewood: a sunny day means she’s stockpiling for more winter; a storm means she’s asleep, winter ending.
  4. 4) Some tales say Cailleach drinks from the well of youth at Beltane, becoming Brigid; others frame them as rivals passing the year’s wheel.
  5. 5) By Samhain, Cailleach rises again, taking the land back into cold, repeating the cycle.

Context & symbolism

The dual figures personify seasonal change and female archetypes: hag/maiden, cold/warmth, decay/renewal. Hearth craft (smithing, poetry) ties Brigid to culture; stone and storm tie Cailleach to raw landscape formation. Imbolc weather lore guides pastoral planning.

Syncretism blends Brigid the goddess with Saint Brigid; Cailleach’s myths vary regionally but retain winter sovereignty.

Use it in play

  • Seasonal powers pass at a festival; PCs can influence which lasts longer.
  • A hag seeks a well of youth; preventing or aiding changes the year’s climate.
  • Weather omen day determines campaign travel conditions.
  • Dual-aspect deity switches roles; offerings must match the aspect.

Comparative threads

  • Seasonal pairs: Persephone/Demeter, Holle/Perchta echo winter/spring shifts.
  • Groundhog/Imbolc lore: Modern weather lore echoes the same watchful day.

Hooks and campaign seeds

  • Secure or sabotage a hag’s wood-gathering to shorten/extend winter.
  • Escort a sacred flame to awaken spring; winter spirits oppose.
  • Find a hidden youth well; decide who drinks and how it alters the land.
