Explain these lines from the poem "The Rime of Ancient Mariner."
And I had done a hellish thing,
And it would work 'em woe:
For all averred, I had killed the bird
That made the breeze to blow.
Ah wretch! said they, the bird to slay,
That made the breeze to blow!
Nor dim nor red, like God's own head,
The glorious Sun uprist:
When the Albatross approached, the men saw this as a good omen. And from that point on, they had good winds to push their sails. Therefore, they associated the Albatross with this good fortune. For some reason, the mariner then kills the Albatross with his crossbow. Then the mariner begins to think that what he did was wrong and the men begin to think that killing the bird will bring them bad luck. "For all averred, I had killed the bird / That made the breeze to blow." They all determined (averred) that the mariner killed the bird (Albatross) that brought them luck and a good wind to sail by.
But in the next lines, the sun rises and brings fog and mist with it. Since this makes sailing difficult, the mariner's crew support the mariner's killing of the bird because now they think that he's killed the bird who brought bad luck: fog and mist.
'Twas right, said they, such birds to slay,
That bring the fog and mist.
When the Albatross was killed, the crew was upset, not because an innocent creature was killed, but because they (selfishly) believed this would end their good luck. However, when the fog and mist arrive, they believe the mariner was right to kill a bird who apparently brought the bad luck (fog and mist). In supporting the mariner's killing, the crew members become accomplices to the mariner's crime. (This is indicated in the gloss: the marginal notes.)
