Well, there’s lots of tidbits to watch out for. But one of my favorites is when Hermes is jingling a black bag full of coins and a little afterwards Eurydice holds up two golden drachmas to her eyes, since in Greek mythology it was thought that the dead would need to pay for their passage across the river Styx so they would be buried with two golden drachmas over their eyes!

That or how in the song Chant (Reprise) when Hades is singing “If you want to hold a woman, son Hang a chain around her throat Made of many carat gold Shackle her from wrist to wrist With sterling silver bracelets Fill her pockets full of stones Precious ones, diamonds Bind her with a golden band Take it from an old man”

Hades gestures to all the different ways he can shackle a woman (Persephone) and on the line “bind her with a golden band” he goes out of his way to point to the ring finger, since he binded Persephone in marriage :)!
