The blue source ( of the sorcerers of Gréasque )

conference: 3 themes (10' each) from the novelist’s point of view (how did this serve the plot), not from the scientist who wants to demonstrate a thesis:

- Celts in Provence?

- Witchcraft, between fantasy and reality...

- Marie-Madeleine in Aix?

- questions answered by participants

- dedication of works.

Friendship and musical atmosphere
