Book IV, Canto XI
Spenser comes back to Florimell, still in Proteus’ dungeon. She is crying about her love for Marinell from the bottom of her rock pit.
Marinell was saved from Britomart’s wound (see III.IV) when his mother recruited Tryphon, the “seagods surgeon”. She keeps Tryphon against his will in case anything ever happens to Marinell again.
At this time two rivers have decided to get married in Proteus’ house. The rest of this canto is a long, LONG list of the names of rivers who come to the wedding. Seriously, that’s it.
