For the Pillar Hall at the Royal Palace, Gustav III ordered an ancient replica, Venus aux belles fesses. The love goddess’ head, though, resembled Ulla von Höpken, Duke Fredrik Adolf’s former mistress. Her uncle, councillor von Fersen, tried but failed to get Sergel to lessen the likeness: the king wanted to have a go at his brother Fredrik Adolf for taking the wrong side in the family row over the crown prince’s legitimacy.
