Valetudo, or Glanis, was a Celtic healing goddess, who was associated with Hygeia.
She was associated with a healing spring at the town of Glanum in the Alpilles mountains of Provence.
There are cisterns at the site of the springs where pilgrims may have bathed. Near one of them an altar to Glanis and the Glanicae was set up. The Glanicae were a triad of local mother goddesses associated with the healing springs.
The town, where a shrine to Glanis was erected in the 4th c. BC, was itself named after the goddess. When it became a colony of the Roman Empire, the Romans followed their usual practice by absorbing Glanis into their pantheon in the form of Valetudo.
