P. Vergilius Maro, Aeneid
Theodore C. Williams, Ed.

Messapus came, steed-tamer, Neptune's son,
by sword and fire invincible: this day,
though mild his people and unschooled in war,
he calls them to embattled lines, and draws
no lingering sword. Fescennia musters there,
Aequi Falisci, and what clans possess
Soracte's heights, Flavinia's fruitful farms,
Ciminian lake and mountain, and the groves
about Capena. Rank on rank they move,
loud singing of their chieftain's praise: as when
a flock of snowy swans through clouded air
return from feeding, and make tuneful cry
from their long throats, while Asia's rivers hear,
and lone Cayster's startled moorland rings:
for hardly could the listening ear discern
the war-cry of a mail-clad host; the sound
was like shrill-calling birds, when home from sea
their soaring flock moves shoreward like a cloud.
