In Celtic mythology, Nantosuelta is the goddess of nature the earth, fire, and fertility.
She was a part of the Tuatha Dé Danann and was paired with Sucellus and later on Dagda.
Pseudo-historical texts explain how there is an uncanny resemblance between Nantosuelta and what we know of the Irish goddess The Morrígan who was associated with death and war. Evidence suggests that Nantosuelta was the name given to the goddess The Morrígan after a transformation or joining of new alliances.
The Mediomatrici (Alsace, Lorraine) depicted her in art as holding a round house on a pole and with a crow. Other likely depictions show her with a pot or bee hive. Nantosuelta's round house was a symbol of her connection to the faery habitation of her Irish counterpart and may have symbolized abundance. It was believed that Nantosuelta transformed into a crow on the battlefield, which was an appropriate transformation for the goddess or may have been a metaphor for her ability to powerfully navigate a battlefield.
Nantosuelta is often associated with water and depicted as being surrounded by water. The goddess's name literally translates as 'of winding stream' or 'sun-drenched valley'.
Nantosuelta is attested by statues, and by inscriptions.
In this relief from Sarrebourg, near Metz, Nantosuelta, wearing a long gown is standing to the left. In her left hand she holds a small house-shaped object with two circular holes and a peaked roof. Her right hand holds a patera which she is tipping onto a cylindrical altar. To the right Sucellus stands, bearded, in a tunic with a cloak on his right shoulder. He holds his mallet in his right hand and an olla in his left. Above the figures is a dedicatory inscription and below them in very low relief is bird, of a raven. This sculpture was dated by Reinach, from the form of the letters, to the end of the first century or start of the second century.
