The longest poem by Samuel Taylor Coleridge, at the dawn of the Romantic poets era, if long poems and flights of fancy are for you, here is a LINK to the full text
These illustrations are by Gustave Dore and accompany the text well.
Even without a wikipedia entry pointing it all out, many have probably heard many a reference to this poem in many a way. Referenced in The Simpsons, Firefly, QI, everywhere!
It was considered a GOOD omen to see an Albatross (alive!) at sea, Captain Malcolm Reynolds knew that ;)
If you like metal, Iron Maiden have a brilliant 13 and a half minute spectacular based on the poem. Apart from perhaps demonising the poor little albatross a touch much, it contains lines from the poem and is a brilliant adaptation of it
