With my cross-bow
I shot the ALBATROSS. - This is the first animal in the poem. Obviously the Mariner violates nature when he kills the Albatross.
Beyond the shadow of the ship,
I watched the water-snakes: - He observes the water snakes and eventually blesses them -
A spring of love gushed from my heart,
And I blessed them unaware:
Sure my kind saint took pity on me,
And I blessed them unaware.
