After examining the original, Dr Dieter Koepplin has also confirmed that it was made either by Lucas Cranach the Elder or his son Lucas Cranach the Younger and emphasises the particularly high quality of the execution. He assumes that it was painted around 1538-41 and points in particular to stylistic parallels with the Lucretia in the National Museum in Warsaw, which is dated 1538 (inv. no. Wil 1749, oil on panel, 59 × 40 cm; see Max J. Friedländer and Jakob Rosenberg: Die Gemälde von Lucas Cranach, Basel/Boston/Stuttgart 1979, p. 150, cat. no. 397).
