Begins making the clay model for Jason with the Golden Fleece, cf. A52.
Thiele I, p. 179 (dates the beginning of the model to the late summer of 1802 without giving his sources for this date).
An entry in the diary of Friederike Brun of 27.11.1802 shows that the model was quite advanced by this date. The passage is quoted in Doris and Peter Walser-Wilhelm: Bonstettiana. Briefkorrespondanzen Karl Viktor von Bonstettens und seines Kreises, Göttingen 2002, Vol. IX/I, p. 411.
