| The expressionistic work of the famous contemporary Flemish writer Hugo Claus (b. 1929) has been translated into several languages. He is also a well-known playwright and prominent poet. In 1983 he published his Het Verdriet van Belgii ("The Sorrow of Belgium"), which brought him international recognition. |
