Alfons Mucha, the Moravian-born father of Art Nouveau, spent eighteen years on his life’s work – quite apart from his vast output as a designer of theatrical posters, stained glass, murals, and jewellery – and when he completed the series in 1928, it was displayed here in Prague at the Trade Fair Palace for seven years. Although the paintings were moved to Moravia for safekeeping during the war, it was Mucha’s wish that they should be permanently exhibited in Prague. In a long and protracted battle for a permanent home, the Epic has now returned to its original exhibition space, at least on a temporary basis.
