This just seems fitting…
Mars was one of the lovers of Venus.
Here Mars is asleep and unarmed, while Venus is awake and alert.
The meaning of the painting is Love conquers War.
Love conquers all.
Mars is sleeping the ‘Little Death’ and not even a trumpet in his ear can wake him.
The little satyrs have stolen his lance — a joke to illustrate he is now unarmed.
Venus is still at once alert, awake and obviously victorious.
Let Love Reign
