Byron's "ottava rima" rhymes a b a b a b c c:

"A mighty mass of brick, and smoke, and shipping,
Dirty and dusky, but as wide as eye
Could reach, with here and there a sail just skipping
In sight, then lost amidst the forestry
Of masts; a wilderness of steeples peeping
On tiptoe through their sea-coal canopy;
A huge, dun cupola, like a foolscap crown
On a fool's head—and there is London Town!"
