Then how does breakfast appear in The Odyssey?
The article itself says that breakfast became a more regular occurrence due to longer, fixed workdays. Some people ate breakfast before then, it just wasn't a set routine the way lunch and dinner were.
I think breakfast works pretty well for a farmer's livestyle. So I wonder, if this is really the big exception.
And there was always a break in the morning (at 9 o'clock) from a "second breakfast" - or a small lunch break.
