Malia wrote:Broken Lyre, Keats's middle name was Zeus, actually--after Keats's father's favorite horse. This was one more reason Keats disliked his name. Of course, it was easier for him to comment on how boring the name John was, rather than comment on the reason why he shared his middle name with that of a horse (and a god). It was just another one of those very private areas of his life that haunted him--and I'm sure influenced his poetry in one way or another.
Ha! Ha! You had me going, Malia, for about a heartbeat! I wondered, for about a half a moment -- "In all my readings of Keats, how in the world did I ever miss THAT piece of info!!" [Too bad it's not 01st April!!]
To reiterate what has (probably) already been offered, Keats most likely had no middle name. I, too, have read lots about him, and never once is there any mention of any of the Keatses having middle names (and the Jennings's kids, as well).
