Saturn is represented as an old man, with a scythe in his hand. […] The images of Janus had in one hand a key, to denote his power in heaven, and in the other hand a sceptre to express his authority upon earth. […] Apollo frequently appears with a lyre in his hand. […] She is represented reclining on a pillar, holding in her hand a mask. […] He held in his left hand the horn of plenty, whilst a finger of his right hand was placed upon his lip, to denote silence.
