Auville works with construction cement. Applying techniques used in the construction and ship building industries, he spreads the cement over Ursalite (high-density foam panels), creating pieces ranging in size from one to eight square meters.

Mare Nostrum is part of a body of work where the artist explores the notion of whiteness.

White is pure light (and conversely); It is the optical combination of all colours; But if you combine all the pigments colours, you will get a grey-beige, never a pure white. White is someting else.

In his explorations, Auville works with white cements, a deeply matte (and very white) material.

In Mare Nostrum, three stripes of white cement, some enlighted with marble powder, some just raw, contrast subtly between them.
