Hi Selma,
Not sure if this info applies as it's been a while since your post. I walked the
Camino Frances last year and the year beofre and just fell upon an amazing artist. His name is Antonio and found on the old Roman tack between Triacastela and Sarria. As a rough estimate he must be about an hour or so before Sarria,there is a small sign that says Cafe Alchemista offering tea and coffee and crystal gallery, if you follow that it means going 500 meters off route but it's really worth it.
Antonio during the summer lives in a huge stone house, sat alone in the middle of nowhere. He is doing some amazing artwork using pulverised crystal to create the most unusual pictures.Although the word pictures don't really seem apt for his peices. Some he hangs with a light behind which has a most wonderful effect.The thing I found interesting is the transformation. I am in to crystals and was in complete sync with his abilty to transform a union of energies from various crystal and transform them in to pieces that speak to our subconcious, all his work is around sacred symbols. A true alchemist. In a chamber on the ground floor he has a meditation room and welcomes anyone to take time to reflect there.
He prepares his own crystals by using a hand mortar,hours of work to crush so little.
Antonio is an unassuming gentle man that often has an apprentice with him that can help with communication with pilgrims. He offers a simple cup of tea or coffee and if a tired pilgrim is tired and in need of a peaceful night he will even let you stay the night. A most aimable man with depth and egoless. Definately a place to find inspiration and if the fancy takes you can make arrangements to spend time and share in his craft.
Apart from finding him I didn't see any other artist's, all tucked away doing their thing I guess. But that one find was magical for me.
As I said this maybe too late for you,if so I hope you enjoyed the journey.
