I can only just visualise this, and it's a long time since I saw it, but... if anyone recognises it, or can at least make a plausible guess, I'd be so very grateful.
It's an Eros-and-Psyche pairing. Not modern in style, I'm sure. It's very dark except in the centre where the figures are; the only light comes I think from the oil lamp in Eros' uplifted arm. I remember thinking his wings were rather larger than usual. The lamp oil is just about to drip onto Psyche's exposed breast.
