The Scythian Mount

In thunderous, purple threads,
The mounted Unicorns go
Off to war,---The archer's bone
And sinew bow, in circled
Retreat, fires their missiles
In rains of hell. An army
Marches to close the gap, yet
The wooden shafts of missiles
Pierce the strongest armor as
The horned mounts of Scythians
Trample men in their charge.
