Originally an expressionist, Gilioli discovered Moor, Giacometti and most importantly Brancusi, and became friends with Poliakoff. He then began to create resolutely abstract sculptures. He worked with materials as diverse as marble, metal, painted iron and polished bronze.
His interest in architecture led him to create monumental works and research into habitable sculptures.
He also created many paintings and tapestries. Cyprus revealed the artist's taste for pure colours used in geometric shapes and strictly abstract orientations.
