Their mother learned them modern art and exposed them to Matisse and Picasso painting in Nice and Avignon in Nice and Vallauris in the 70s.

Following him :

Art is not an issue. Only spiritual experience through art is an issue.

This is the Kandinsky lesson

Works of art are only mediums just like sky, wind, or light (or mitsvot!) to experiment the Spiritual that is the real reality.


Brother Marc was monk in La Pierre-Qui-Vire Abbey from 1985 to 1995. He was publisher of the Editions Zodiaque funded by Dom Anglico Surchamps and specialized in Romanesc Art. He worked with specialists like Regine Pernoud, specialist of medieval Charts and invented the digital printing process named : « gravure noire » to obtain impressive contrasts for whit and black pictures.

Spiritual Cans

Brother marc, began his artistic path in a monastery : Abbaye de la Pierre-Qui-Vire (1985 – 1990) formed by monks friends of the cubist Albert Gleize in the 50s. Under this teaching, brother marc specialized in the begining in sacred art (Venice Biennale). He also studied theology during 5 years with responsibilities in this field for his monastic community.

On day of 1990 readding a sermon of Paul Tillich brother marc realized that sacred art path leed him nowhere.

The words « deep » and « depth » are used in our daily life, in poetry and philosophy, in the Bible, and in many other religious documents, to indicate a spiritual attitude, although the words themselves are taken from a spatial experience. Depth is a dimension of space; yet at the same time it is a symbol for a spiritual quality. Most of our religious symbols have this character, reminding us of our finitude and our bondage to things that are visible…There is…a great wisdom in our language. It is the embodiment of innumerable experiences of the past.

“The Depth of Existence” by Paul Tillich, a meditation on the words “depth” and “deep”


… and decided to work on human fence (havadala, « separation » in hebrew from leavdil, separate).

Living in a cloister, owning not even his own skin. (a monk own nothing none his own body)

He found cans. The only things entering in the cloister. Cans were only recipient and they were destoyed after usage. They were poors and vulnerables. It was the perfect symbol of humanity. Brother marc decided to work with that kinf of materials.

All visible things have a surface. It is the first thing which appears to us. Face, Skin, House, Cell membrane. Life is enclosed and invisible inside. We must penetrate below the surfaces in order to learn what people and things really are.

Throughout this work, brother marc critiqued the traditional monotheistic idea of God in Christianity as a being alongside the world with definable properties and visible attributes.

“ Out of the depths have I cried unto thee, O Lord,”
