Argonautica: Book 2: line 714

(2.714-719) Now when they had celebrated him with dance and song they took an oath with holy libations, that they would ever help each other with concord of heart, touching the sacrifice as they swore; and even now there stands there a temple to gracious Concord, which the heroes themselves reared, paying honour at that time to the glorious goddess.

(2.720-751) Now when the third morning came, with a fresh west wind they left the lofty island. Next, on the opposite side they saw and passed the mouth of the river Sangarius and the fertile land of the Mariandyni, and the stream of Lycus and the Anthemoeisian lake; and beneath the breeze the ropes and all the tackling quivered as they sped onward. During the night the wind ceased and at dawn they gladly reached the haven of the Acherusian headland. It rises aloft with steep cliffs, looking towards the Bithynian sea; and beneath it smooth rocks, ever washed by the sea, stand rooted firm; and round them the wave rolls and thunders loud, but above, wide-spreading plane trees grow on the topmost point. And from it towards the land a hollow glen slopes gradually away, where there is a cave of Hades overarched by wood and rocks. From here an icy breath, unceasingly issuing from the chill recess, ever forms a glistening rime which melts again beneath the midday sun. And never does silence hold that grim headland, but there is a continual murmur from the sounding sea and the leaves that quiver in the winds from the cave. And here is the outfall of the river Acheron which bursts its way through the headland and falls into the Eastern sea, and a hollow ravine brings it down from above. In after times the Nisaean Megarians named it Soonautes when they were about to settle in the land of the Mariandyni. For indeed the river saved them with their ships when they were caught in a violent tempest. By this way the heroes took the ship through the Acherusian headland and came to land over against it as the wind had just ceased.

(2.752-773) Not long had they come unmarked by Lycus, the lord of that land, and the Mariandyni -- they, the slayers of Amycus, according to the report which the people heard before; but for that very deed they even made a league with the heroes. And Polydeuces himself they welcomed as a god, flocking from every side, since for a long time had they been warring against the arrogant Bebrycians. And so they went up all together into the city, and all that day with friendly feelings made ready a feast within the palace of Lycus and gladdened their souls with converse. Aeson's son told him the lineage and name of each of his comrades and the behests of Pelias, and how they were welcomed by the Lemnian women, and all that they did at Dolionian Cyzieus; and how they reached the Mysian land and Cius, where, sore against their will, they left behind the hero Heracles, and he told the saying of Glaucus, and how they slew the Bebrycians and Amycus, and he told of the prophecies and affliction of Phineus, and how they escaped the Cyanean rocks, and how they met with Leto's son at the island. And as he told all, Lycus was charmed in soul with listening; and he grieved for Heracles left behind, and spake as follows among them all:

(2.774-810) "O friends, what a man he was from whose help ye have fallen away, as ye cleave your long path to Aeetes; for well do I know that I saw him here in the halls of Dascylus my father, when he came hither on foot through the land of Asia bringing the girdle of warlike Hippolyte; and me he found with the down just growing on my cheeks. And here, when my brother Priolas was slain by the Mysians -- my brother, whom ever since the people lament with most piteous dirges -- he entered the lists with Titias in boxing and slew him, mighty Titias, who surpassed all the youths in beauty and strength; and he dashed his teeth to the ground. Together with the Mysians he subdued beneath my father's sway the Phrygians also, who inhabit the lands next to us, and he made his own the tribes of the Bithynians and their land, as far as the mouth of Rhebas and the peak of Colone; and besides them the Paphlagonians of Pelops yielded just as they were, even all those round whom the dark water of Billaeus breaks. But now the Bebrycians and the insolence of Amycus have robbed me, since Heracles dwells far away, for they have long been cutting off huge pieces of my land until they have set their bounds at the meadows of deep-flowing Hypius. Nevertheless, by your hands have they paid the penalty; and it was not without the will of heaven, I trow, that he brought war on the Bebrycians this day -- he, the son of Tyndareus, when he slew that champion. Wherefore whatever requital I am now able to pay, gladly will I pay it, for that is the rule for weaker men when the stronger begin to help them. So with you all, and in your company, I bid Dascylus my son follow; and if he goes, you will find all men friendly that ye meet on your way through the sea even to the mouth of the river Thermodon. And besides that, to the sons of Tyndareus will I raise a lofty temple on the Acherusian height, which all sailors shall mark far across the sea and shall reverence; and hereafter for them will I set apart outside the city, as for gods, some fertile fields of the well-tilled plain."
