Let the colour, shape and movement of Antwerp artist Marthe Donas' modernism enchant you. For the first time, an exhibition shows her central role in the international avant-garde, alongside the work of her partner at the time, Ukrainian sculptor Alexander Archipenko. Side by side, they take their innovations to a higher level. Surrounded by masterpieces by artist friends such as Mondrian, Modigliani, Goncharova and Vassilieff, the oeuvre and story of this forgotten leading lady offer a glimpse into a modernism that is colourful, groundbreaking and surprisingly gender-diverse.
