I thought the main character of his novel was called Naruto (no idea what his book was called, but it makes no sense to name it after someone else).
Tale of the Gallant Jiraiya was a Japanese legend / episode title.
I rewatched the episode where Jiraiya dies, he mentioned his novel the tale of the gallant Jiraiya. But it was also possible he meant the end of his own tale. hmmm
