The lines are:
With never a whisper in the main
Off shot the spectre ship:
And stifled words & groans of pain
Mix’d on each {murmuring / trembling} lip
[And] We look’d round & we look’d up
And Fear at our hearts as at a Cup
The Life-blood seem’d to sip
The Sky was dull & dark the Night,
The Helmsman’s Face by his lamp gleam’d bright,
From the Sails the Dews did drip
Till rose clomb above the Eastern Bar
The horned moon, with one bright Star
Within its nether Tip.
One after one, by the star-dogg’d moon, etc.
These lines are from Coleridge’s notebook (number eleven) and were reportedly written in October, 1806.
The jotted down lines are a section of “The Rime of the Ancient Mariner” (lines 201-212 from the 1817 edition).
