Virgil, Aeneid

III.30; plant bleeds when ripped from its roots; groans

III.520-9; prophetess Sybil puts her vision of the Fates on leaves ("signs on leaves") that are arranged in verses; when the doors to her cave open, though, the leaves are scattered, and she does not rearrange them in the correct order; VI.97, Sibyl is implored to sing the Fates instead of putting them on leaves; all the doors of her house open and sing her answer

VI.815; souls hover around Lethe like bees, waiting to be born
