The words wrinkled and crawls may seem odd at first; but if you realize that the sea is being looked at from a great height, you will see how appropriately they describe the movement of the waves, reduced in appearance to mere wrinkles.
이 문장 해석이 잘안되요.

→ wrinkled and crawls라는 단어는 처음에는 이상해보일지도 모른다. 하지만 바다가 엄청 높은곳에서 바라봐진다는 것을 깨닫는다면, 여기까지 해석했는데 그 뒤에를 못하겠어요

특히 reduced in appearance to mere wrinkles를요.

해석 도와주세요 ^^;;

Alfred, Lord Tennyson 의 The Eagle이라는 시를 설명해 놓은 거예요. 참고로 시는 아래와 같구요.
He clasps the crag with crooked hands;
Close to the sun in lonely lands,
Ringed with the azure world, he stands.

The wrinkled sea beneath him crawls;
He watches from his mountain walls,
And like a thunderbolt he falls.
