Trier, Porta Nigra
Trier, Porta Nigra.

Post ipse* dum deficientem a se oppugnat civitatem, sagittae ictu interiit, relicta uxore Semirame cum duobus filiis Trebeta et Nina. quorum primus, videlicet Trebetas, ex regina quadam Chaldeorum, quam ante Semiramem duxerat, Ninas autem de Semirame natus erzat. occiso ergo Nino, Semiramis privignum suum Trebetam maritum ducere voluit, eumque renitentem et execrantem, invidia ac libidine stimulata, tam diu persecuta est, donec eum patria pelleret et regno. pulsus igitur, dum diu longeque sedes vagando quaereret et non inveniret, coepit ex diuturni itineris fatigatione taedere, et ubinam sibi fata quiescendum consulerent, missione sortis inquirere. sors optulit Europam, quae est tertia pars orbis, licet quidam secundam diffiniant et Africam non per se partem esse set ad Europam pertinere contendant. transfretato mari mediterraneo, quod ab Asia dividit Europam, per vasta solitudinum et invia saltuum venit ad Mosellam, in cujus littore repperit vallem speciosam, aquis irriguam, silvis nemorosam, montibus undique circumseptam. captus amenitate loci, ibidem subsistere delegit, urbemque constituit, quam ex suo nomine Treberim appellavit.

* Ninus, the first Assyrian king. In the next chapter we are informed that all this supposedly took place 1250 years before the founding of Rome.

Afterwards, while Ninus was attacking a city that defected from him, he was wounded by an arrow and died, leaving his wife Semiramis and their two sons Trebetas and Ninas. The first of those, Trebetas, he had from some Chaldean queen that he was married to before Semiramis; but Ninas was born from Semiramis. So when Ninus was killed, Semiramis wanted to marry her son-in-law Trebetas, but when he proved resistant and disgusted, she, incited by spite and lust, persecuted him for a long time, until finally she ejected him from the country and from his royal state. So, having been ejected, while he wandered far and wide in search of a place to live, but couldn’t find any, he began to get sick of the exhaustion brought on by his long journey, and he turned to the throwing of lots to find out where the Fates advised him to find rest. The lot suggested Europe, which is the third part of the world, although some define it as the second, claiming that Africa is not a part in itself but belongs to Europe. Having sailed across the Mediterranean sea, which divides Europe from Asia, through vast deserts and inaccessible mountain passes, he came to the Moselle river, on the banks of which he found a lovely valley, well-watered, covered with woods, and girded on all sides by mountains. Captivated by this lovely place, he chose to halt there, and founded a city, which he named Treberis after himself. (tr. David Bauwens)
