There Angelica pretends she has fallen in love with him, and accompanies him when he returns to France under pretext of becoming a Christian.

Their way again lies through the forest of Arden, where this time Angelica drinks from the fountain of hatred.

All her former love for Rinaldo therefore vanishes, and, as the latter has at the same time partaken of the water of love, their parts are reversed, for it is he who now pursues Angelica whom he previously loathed.

His attentions so incense Orlando that he begins a fight, which Charlemagne checks, declaring that Angelica--who is placed in charge of Duke Namus--shall be awarded to the warrior who distinguishes himself most in the coming war.
In the course of this campaign these two knights meet with many adventures, and are accompanied by Bradamant--Rinaldo's sister--who manfully fights by their side.

Among their opponents the most formidable are Rogero and the pagan Rodomont, whose boastful language has given rise to the term rodomontade.
