The gardens of Vaux-le-Vicomte are terraced and end at a hill overlooking canals and grottos. In the center of this beautiful hill is a statue of mythological significance. Who is the subject of the statue, and what event (or feat, shall we say), does the statue "commemorate."
On the hill at the end of the gardens is a statue of Hercules. He is depicted standing and resting, leaning on something, after performing the last of his "labors" or feats. As far as I can tell, it does not show him performing any particular feat.
