Here, divine power begins to be personified, but is still experienced as being strongly embedded in nature. Divinities may be depicted in human or semi-human form, or perceived as possessing human attributes, but they are still based in the natural world.

Every spring reflects the Well of Wisdom guarded by Segais or Nechtan.
