Strabo Geography 5.2.6

[6] The country of the Volaterrani ¹ is washed by the sea. Their city is situated in a deep hollow on the top of a high hill. The wall of the city is built round its summit, which is flat and precipitous on every side. From its base, the ascent upward is fifteen stadia, steep and difficult. Here certain of the Tyrrhenians and of those proscribed by Sulla, ² took their stand, and having organized four bands, sustained a siege for two years, and at last secured articles of truce before surrendering the place. Poplonium is situated on a lofty promontory, which projects into the sea, and forms a chersonesus. It likewise sustained a siege about the same time. This little place is now deserted, with the exception of the temples and a few houses; the sea-port, which is situated at the root of the mountain, is better inhabited, having both a small harbour and ship-sheds. This appears to me the only one of the ancient Tyrrhenian cities situated on the sea; the reason being that this territory affords no harbours. The founders [of the cities] therefore either avoided the sea altogether, or threw up fortifications in order that they might not become the ready prey of those who might sail against them. On the summit [of the cape] there is a look-out for thunnies. ³ From this city there is an indistinct and distant view of Sardinia. Cyrnus, ⁴ however, is nearer, being distant from Sardinia about 60 stadia. While Aethalia ⁵ is much nearer to the continent than either, being distant therefrom only 300 ⁶ stadia, and the same number from Cyrnus. Poplonium is the best starting-place to any of the three mentioned islands. We ourselves observed them from the height of Poplonium, in which place we saw certain mines which had been abandoned, we also saw the craftsmen who work the iron brought from Aethalia; for they cannot reduce it into bars in the furnaces on the island, and it is therefore transferred direct from the mines to the continent. There is another remarkable circumstance, that the exhausted mines of the island in course of time are again refilled similarly to what they say takes place at the platamones ⁷ in Rhodes, the marble-quarries in Paros, and the salt-mines in India, mentioned by Clitarchus. Eratosthenes was therefore incorrect in saying that from the mainland you could neither see Cyrnus nor Sardinia; and so was Artemidorus in his assertion, that both these places lay in the high sea at a distance of 1200 stadia. For whatever others might, I certainly could never have seen them at such a distance, however carefully I had looked, particularly Cyrnus. Aethalia has a harbour named Argoiis, ⁸ derived, as they say, from the [ship] Argo, Jason having sailed hither, seeking the abode of Circe as Medea wished to see that goddess; and that from the sweat scraped off by the Argonauts and hardened, are formed the variegated pebbles now seen on the beach. ⁹ This and similar traditions prove what we before stated, that Homer did not invent them all himself, but, hearing the numerous current stories, he merely transferred the scenes to other localities and exaggerated the distances: as he makes Ulysses wander over the ocean, so does he narrate of Jason, as he too had been renowned for his travels: and the same he likewise relates of Menelaus. This is what we have to say of Aethalia.
