Mary Christea was born on 21 March 1949 in Athens, Greece. She studied at the Athens School of Fine Arts - ASFA (1969-1973) painting with Lefteris Kanakakis, Yannis Moralis and Nikos Nikolaou, and mosaic under Irene Voila. She furthered her studies at the Staatliche Hochschule für Bildende Künste, Berlin (1973-1975) in painting with Raimund Girke, art history with Dr Walter Hesse, philosophy with Dr Heinz Wenzel, and literature with Dr Gurt Gruetzmacher. In 1987 her work reveals influences by Greek classical art, whereby she used the relief technique in her investigation of pictorial solutions to the problem of the relationship between the figure and its space. Subsequently she used the same technique in other artforms - drawing, construction, and photographic collage. In the period 1998-2000 she produced motor constructions, where the movement of the image plays the leading role. In the period 2000-2001 she produced videos (Perpetual Journey & Asymmetrical Circles) along her initial speculation concerning the behaviour of the figure and its relation to space, adopting new means of expression. In 2002 she produced Perpetual Journeys based on her previous videos, on the subject of the relation of women with their environment. In the period 2003-2004 she produces Frozen (three projections) on the theme of the imprints that memories leave on the body.
