Lyric Poem · Nature

An Allegory

by Percy Bysshe Shelley

1A portal as of shadowy adamant

2Stands yawning on the highway of the life

3Which we all tread, a cavern huge and gaunt;

4Around it rages an unceasing strife

5Of shadows, like the restless clouds that haunt

6The gap of some cleft mountain, lifted high

7Into the whirlwinds of the upper sky.

8And many pass it by with careless tread,

9Not knowing that a shadowy ...

10Tracks every traveller even to where the dead

11Wait peacefully for their companion new;

12But others, by more curious humour led,

13Pause to examine; — these are very few,

14And they learn little there, except to know

15That shadows follow them where'er they go.

How this poem works

Measured from the text on this page, not copied from a summary. Counts are approximate: syllables and rhymes come from the CMU Pronouncing Dictionary, which models General American English, so dialect, older pronunciation, and performance can all change what you hear.

Shape
15 lines · 2 stanzas of 7–8 lines
Line length
Lines run 9-11 syllables (median 10), consistent with pentameter. No single length dominates, which is normal once elision and contraction are in play.
The poem’s silhouette — approximate syllables per line, measured from the text above. Even bars mean a measured line; ragged bars mean the poem sets its own widths.
