Then he replied briefly, so: ‘How gladly I know, and
welcome you, bravest of Trojans! How it brings back
your father’s speech, the voice and features of noble Anchises!
For I recall how Priam, son of Laomedon, visiting the realms
of his sister, Hesione, and seeking Salamis,
came on further to see the chill territories of Arcadia.
In those days first youth clothed my cheeks with bloom,
and I marvelled at the Trojan leaders, and marvelled
at the son of Laomedon himself: but Anchises as he walked
was taller than all. My mind burned with youthful desire
to address the hero, and clasp his hand in mine:
I approached and led him eagerly inside the walls of Pheneus.
On leaving he gave me a noble quiver
of Lycian arrows, a cloak woven with gold,
and a pair of golden bits, that my Pallas now owns.
So the hand of mine you look for is joined in alliance,
and when tomorrow’s dawn returns to the earth,
I’ll send you off cheered by my help, and aid you with stores.
Meanwhile, since you come to us as friends, favour us
by celebrating this annual festival, which it is wrong
to delay, and become accustomed to your friends’ table.’
When he had spoken he ordered the food and drink
that had been removed to be replaced, and seated
the warriors himself on the turf benches.
He welcomed Aeneas as the principal guest, and invited him
to a maple-wood throne covered by a shaggy lion’s pelt.
Then the altar priest with young men he had chosen
competed to bring on the roast meat from the bulls,
pile the baked bread in baskets, and serve the wine.
Aeneas and the men of Troy feasted on an entire
chine of beef, and the sacrificial organs.
When hunger had been banished, and desire for food sated,
King Evander said: ‘No idle superstition, or ignorance
of the ancient gods, forced these solemn rites of ours,
this ritual banquet, this altar to so great a divinity, upon us.
We perform them, and repeat the honours due,
Trojan guest, because we were saved from cruel perils.
Now look first at this rocky overhanging cliff, how its bulk
is widely shattered, and the mountain lair stands deserted,
and the crags have been pulled down in mighty ruin.
There was a cave here, receding to vast depths,
untouched by the sun’s rays, inhabited by the fell shape
of Cacus, the half-human, and the ground was always warm
with fresh blood, and the heads of men, insolently
nailed to the doors, hung there pallid with sad decay.
Vulcan was father to this monster: and, as he moved
his massive bulk, he belched out his dark fires.
Now at last time brought what we wished, the presence
and assistance of a god. Hercules, the greatest of avengers,
appeared, proud of the killing and the spoils of three-fold
Geryon, driving his great bulls along as victor,
and his cattle occupied the valley and the river.
And Cacus, his mind mad with frenzy, lest any
wickedness or cunning be left un-dared or un-tried
drove off four bulls of outstanding quality, and as many
heifers of exceptional beauty, from their stalls.
and, so there might be no forward-pointing spoor, the thief
dragged them into his cave by the tail, and, reversing
the signs of their tracks, hid them in the stony dark:
no one seeking them would find a trail to the cave.
Meanwhile, as Hercules, Amphitryon’s son, was moving
the well-fed herd from their stalls, and preparing to leave,
the cattle lowed as they went out, all the woods were filled
with their complaining, and the sound echoed from the hills.
One heifer returned their call, and lowed from the deep cave,
and foiled Cacus’s hopes from her prison.
At this Hercules’s indignation truly blazed, with a venomous
dark rage: he seized weapons in his hand, and his heavy
knotted club, and quickly sought the slopes of the high mountain.
Then for the first time my people saw Cacus afraid, confusion
in his eyes: he fled at once, swifter than the East Wind,
heading for his cave: fear lent wings to his feet.
As he shut himself in, and blocked the entrance securely,
throwing against it a giant rock, hung there in chains
by his father’s craft, by shattering the links, behold
Hercules arrived in a tearing passion, turning his head
this way and that, scanning every approach, and gnashing
his teeth. Hot with rage, three times he circled the whole
Aventine Hill, three times he tried the stony doorway in vain,
three times he sank down, exhausted, in the valley.
A sharp pinnacle of flint, the rock shorn away
on every side, stood, tall to see, rising behind
the cave, a suitable place for vile birds to nest.
He shook it, where it lay, it’s ridge sloping towards the river
on the left, straining at it from the right, loosening its deepest
roots, and tearing it out, then suddenly hurling it away,
the highest heavens thundered with the blow,
the banks broke apart, and the terrified river recoiled.
But Cacus’s den and his vast realm stood revealed,
and the shadowy caverns within lay open,
no differently than if earth, gaping deep within,
were to unlock the infernal regions by force, and disclose
the pallid realms, hated by the gods, and the vast abyss
be seen from above, and the spirits tremble at incoming light.
So Hercules, calling upon all his weapons, hurled missiles
at Cacus from above, caught suddenly in unexpected daylight,
penned in the hollow rock, with unaccustomed howling,
and rained boughs and giant blocks of stone on him.
He on the other hand, since there was no escape now
from the danger, belched thick smoke from his throat
(marvellous to tell) and enveloped the place in blind darkness,
blotting the view from sight, and gathering
smoke-laden night in the cave, a darkness mixed with fire.
Hercules in his pride could not endure it, and he threw himself,
with a headlong leap, through the flames, where the smoke
gave out its densest billows, and black mist heaved in the great cavern.
Here, as Cacus belched out useless flame in the darkness,
Hercules seized him in a knot-like clasp, and, clinging, choked him
the eyes squeezed, and the throat drained of blood.
Immediately the doors were ripped out, and the dark den exposed,
the stolen cattle, and the theft Cacus denied, were revealed
to the heavens, and the shapeless carcass dragged out
by the feet. The people could not get their fill of gazing
at the hideous eyes, the face, and shaggy bristling chest
of the half-man, and the ashes of the jaw’s flames.
Because of that this rite is celebrated, and happy posterity
remembers the day: and Potitius, the first, the founder, with
the Pinarian House as guardians of the worship of Hercules,
set up this altar in the grove, which shall be spoken of for ever
by us as ‘The Mightiest’, and the mightiest it shall be for ever.
Come now, O you young men, wreathe your hair with leaves,
hold out wine-cups in your right hands, in honour of such great glory,
and call on the god we know, and pour out the wine with a will.’
He spoke, while grey-green poplar veiled his hair
with Hercules’s own shade, hanging down in a knot of leaves,
and the sacred cup filled his hand. Quickly they all poured
a joyful libation on the table, and prayed to the gods.
