I know this is Assonance

“ The ship was cheer’d, the Harbour clear’d

“ Twas sad as sad could be;”

But I need to know the effect of what is the tone or mood or theme in these two lines in the poem "The Rime of the Ancient Mariner" by Samuel Taylor Coleridge.

Im thinking that they are at a breaking point in there life because there ship broke ? and now can't do anything about it

See my last post in response to your question about the bright sun below. What is the context within the poem?

In other words, read the poem, Ciara. You cannot know the tone or mood based on one line alone.

Yeah I replied to it :)

Yes, you did. And by "biting" on my suggestion that night brings mystery, you showed me you have not read the poem. Until you do, please don't ask these questions again.

He holds him with his glittering eye—

The Wedding-Guest stood still,
And listens like a three years' child: 15
The Mariner hath his will.

The Wedding-Guest sat on a stone:
He cannot choose but hear;
And thus spake on that ancient man,
The bright-eyed Mariner. 20

'The ship was cheer'd, the harbour clear'd,
Merrily did we drop
Below the kirk, below the hill,
Below the lighthouse top.

The Sun came up upon the left, 25
Out of the sea came he!
And he shone bright, and on the right
Went down into the sea.

I did read the whole poem but its just kinda confusing because its different words , Some words aren't even in the dictionary.

The fair breeze blew, the white foam flew,

The furrow followed free;
We were the first that ever burst
Into that silent sea.

Down dropped the breeze, the sails dropped down,
‘Twas sad as sad could be;
And we did speak only to break
The silence of the sea!

All in a hot and copper sky,
The bloody sun, at noon,
Right up above the mast did stand,
No bigger than the moon.

Which words aren't in the dictionary?

I just need help with what the sentences mean ?

Yes, I see you do not understand. The ship sets sail, clearing the harbor (leaving behind the kirk (church), lighthouse, etc. The weather is fine, the breeze propels the sailing ship, until they enter a very, very calm place in the ocean. Then, with no breeze, the sun becomes hot, and there is no sound of the ocean or the breeze.

They are in the "doldrums." That word is in the dictionary.
