(Also spelled idyll.)

There are two separate meanings for ‘idyl.’ In the first meaning, it is simply a synonym for eclogue. In its other meaning, an idyl is a narrative poem written in high language that deals with an epic or romantic theme. Probably the best-known idyl is Alfred Lord Tennyson’s Idylls of the King, from which the lines below are taken:
.

.

For many a petty king ere Arthur came
Ruled in this isle, and ever waging war
Each upon other, wasted all the land;
And still from time to time the heathen host
Swarmed overseas, and harried what was left.
And so there grew great tracts of wilderness,
Wherein the beast was ever more and more,
But man was less and less, till Arthur came.
