Which of the following lines contain a metaphor?
——————————————
1) Thou from whose unseen presence the leaves dead Are driven, like ghosts from an enchanter fleeing
2)Like the bright hair uplifted from the head Of some fierce Mænad, ev’n from the dim verge Of the horizon to the zeniths height - The locks of the approaching storm. Thou dirge
3) A heavy weight of hours has chain’d and bow’d One too like thee- tameless, and swift, and proud
4) Be through my lips to unawaken’d earth
The trumpet of a prophecy
