dorian gray’s phantasmagoria

“Its curtains were of damask, with leafy wreaths and garlands, figured upon a gold and silver ground, and fringed along the edges with broideries of pearls, and it stood in a room hung with rows of the queen’s devices in cut black velvet upon cloth of silver.”

i’m trying to picture this. stood in a room hung with rows of queen’s devices in cut black velvet? what does “devices” mean in this context? i’m picturing various objects hanging from rows of fabric. makes no sense.
