The Three Horses by George MacDonald

Three horses rode
three men in armor
black spears lances and a message to deliver

each to a different arena
to plunge in with effrontery
to zig and zag between the skulls and serpentine dragons
to be stricken by thickets and snarling bosoms

to be steady to be swift
to by-pass sheep and goat
stand a-jar in the face of a World

Three horses rode
three men in armor
and a message to be told
