Discover the ancient and mysterious world of the Celts, a culture from the Iron Age that inhabited Western Europe for over a thousand years before the Roman Empire. Learn how their belief system was shaped by reverence for nature and was in harmony with the changing seasons - how their solar year was divided into a 'light half' and a 'dark half' and marked by four major festivals. Explore the pantheon of Celtic deities, where goddesses were worshipped equally alongside their male counterparts - the Tuatha Dé Danann, a supernatural people from Irish mythology, whose name translates to 'the people of the goddess Danu.' Alongside Danu were Brigid and the Morrigan, a complex and multifaceted goddess. Celtic mythology is filled with dragons and giants and bequeaths us stories about the Púca - the true origin of Halloween - the changelings, the Bean Sí - the Banshee - the Leprechauns - little goblins - and the Aos Sí - 'the people of the hills' - or fairies. The oral tradition of the Celts tells many heroic tales. We gain insight into the four great cycles of Ireland's mythological history with its many legendary figures, from the demigod Cú Chulainn to Fionn Mac Cumhaill. And in the final chapter, we delve into the Arthurian legend, which has its roots in Welsh mythology.
