Judgment of Paris

[Jona Lendering]

Is the lefthand figure (the true Hermes, by David's reckoning) plucking the golden apple from the tree?

A tempting idea, and I checked the larger file, but no. Besides, that apple had already been thrown prior to the arrival of the goddesses; on the other hand, it would not have been the only ancient work of art that is "illogical", showing things simultaneously that did not happen at the same time. So it might have been possible.
