The Pillars of Hercules once passed, the travelers beheld the sirens, and, landing once more, were joined by Corineus, who proposed to accompany them.
Brutus then coasted along the shores of the kingdom of Aquitaine and up the Loire, where his men quarreled with the inhabitants.

He found himself involved in a fierce conflict, in which, owing to his personal valor and to the marvelous strength of Corineus, he came off victor in spite of the odds against him.
In this battle Brutus' nephew, Turonus, fell, and was buried on the spot where the city of Tours was subsequently built and named after the dead hero.

After having subdued his foes, Brutus embarked again and landed on an island called Albion.

Here he forced the giants to make way for him, and in the encounters with them Corineus again covered himself with glory.
We are told that the first germ of the nursery tale of Jack the Giant Killer is found in this poem, for Corineus, having chosen Corinea (Cornwall) as his own province, defeated there the giant Goemagot, who was twelve cubits high and pulled up an oak as if it were but a weed.

Corineus, after a famous wrestling bout, flung this Goemagot into the sea, at a place long known as Lam Goemagot, but now called Plymouth.
[Sidenote: The founding of London.] Brutus pursued his way, and finally came to the Thames, on whose banks he founded New Troy, a city whose name was changed in honor of Lud, one of his descendants, to London.
