In
Latin poetry Oestreminis ("Extreme West") was a name given to the territory of what is today modern
Portugal and
Galicia, comparable to Finis terrae, the "end of the earth" from a Mediterranean perspective. Its inhabitants were named Oestrimni from their location.
In Ora Maritima ("Seacoasts"), a poem inspired by a much earlier Greek mariners' periplus,
Rufus Avienius Festus, Roman poet of the fourth century CE known for his pieces on geographical subjects, records that Oestriminis was peopled by the Oestrimni, a people who had lived there for a long time, and had to run away from their native lands after an invasion of
serpents. His fanciful account has no archeological or historical application, but the poetical name has sometimes been ambitiously applied to popularized accounts of the Paleolithic inhabitants of Atlantic Iberia.
The expulsion of the Oestrimni, from Ora Maritima:
Post illa rursum quae supra fati sumus,
magnus patescit aequoris fusi sinus
Ophiussam ad usque. rursum ab huius litore
internum ad aequor, qua mare insinuare se
dixi ante terris, quodque Sardum nuncupant,
septem dierum tenditur pediti via.
Ophiussa porro tanta panditur latus
quantam iacere Pelopis audis insulam
Graiorum in agro. haec dicta primo Oestrymnis est
locos et arva Oestrymnicis habitantibus,
post multa serpens effugavit incolas
vacuamque glaebam nominis fecit sui.
Back after the places we spoke of above,
there opens a great bay filled with water,
all the way to Ophiussa. Back from the shore of this place,
to the inland water, through which I said before that the sea insinuates itself
