The Wren, Celtic King of the Birds, symbolized wit and sublety. Sacred to the Druids, the musical notes of the cunning Wren were used for divination. As with many other birds, the Wren was considered to be a messenger from the deities.
The Wren once competed with the other birds for supremacy and answered the challenge of the Eagle to race toward the Sun. When the Eagle could fly no higher, the Wren, which has been nestling within the Eagle’s feathers jumped upon the back of the Eagle and flew a few inches higher prior to proclaiming himself King of the Birds, and thus humiliating the Eagle.
The Wren fell under the particular protection of Taranis, Celtic God of Thunder.
