Answer 2

The Celts worshiped a variety of deities that represented different aspects of nature, such as the sun, moon, and animals. They also believed in spirits that inhabited natural elements like trees, rivers, and mountains. Offerings and sacrifices were made to these deities and spirits to ensure protection, prosperity, and fertility.

Answer 3

Like other pagan peoples, the Celts were polytheists who worshipped pantheons of deities. These pantheons varied from society to society among the Celts, and there were many purely local gods and goddesses. However, there were a few deities who seem to have been represented in multiple Celtic societies, although their names were spelled differently from place to place. Brigid, Lugh and Ogma are examples.
