Final answer:
In 'The Rime of the Ancient Mariner', the sailors celebrated when they first spotted the Albatross, welcoming it as a sign of good luck.
Step-by-step explanation:
In The Rime of the Ancient Mariner, the sailors initially reacted with joy and celebration when they spotted the Albatross. As the bird flew through the fog and ice, the sailors saw it as a good omen and welcomed it with food and play. It was seen as a spiritual figure, symbolizing hope and guidance through their treacherous journey. The mariner's fatal mistake was to shoot the Albatross, which brought disastrous consequences upon himself and his fellow sailors - a central point of the poem's moral narrative about the respect of all God's creatures.
