Immortal Three (The)

Homer, Dante, and Milton.

"Three poets, in three distant ages born,
Greece, Italy, and England did adorn;
The first in loftiness of thought surpassed,
The next in majesty; in both the last;
The force of nature could no farther go,
To make a third, she joined the other two."

Dryden: A Tablet to the Memory of John Milton (St. Mary-le-Bow, Cheapside).

It was originally in the church of All Hallows, Bread Street.
