I really hesitate to throw my example into the mix, but:

I don't have much use for more testicles than I already have, but money is always useful. However, my jeton is not for sale today. The image is definitely a "celestial" shield. I'm not sure I could easily relocate a cgb image of one such shield leaning against a wall with some weapons illustrated on a spectacular jeton. It is in one of their auctions (not the jeton catalogs) and it went for something between $500 and $1000 if I remember right. It is a spectacular piece. I will post a link if I stumble across it again.
The opportune time refers to the battle of Troy when the gods threw down a "celestial shield" at an opportune time. That is a much too short reference to a much longer story. In any event, French symbolism drew heavily on the legends of Troy, etc. in the 1600s.
