They had these Cupids with and object my mom calls a loving cup. Has anyone heard of that term?
Sure. It would have been a cup for a function - such as a wedding - and would have been made with two handles, so that two (presumably husband and wife) could drink from it. It would have been made from the same metal as the candlesticks, and would have formed a kind of garniture for display. The candles may have been lit simultaneous to drinking, to symbolize devotion and longevity. Incidentally, the candlesticks look like spelter or old pewter to me.
Sounds pretty cool. What happened to the cup?
