This isn’t about a Straight Dope column _per se_, but about a quiz answer in _More of the Straight Dope_. The question is on page 222, and the answer (such as it is) is on page 473-4. We are asked to believe that “Nicolaus Copernicus, the astronomer, was the first man to butter his bread.” The explanation goes

> [@](#):

> … Copernicus discovered the magic of buttered bread when he was put in charge of defending the besieged castle of Allenstein in Prussia, where he was nominally employed as a canon of the Cathedral of Frauenberg. This being the early sixteenth century, Copernicus found he was losing as many soldiers to the plague as he was to the enemy. Turning his powerful mind to the problem, he hypothesized a link between the plague and the vile food the soldiers were eating. (Apparently they had Cheez Whiz even then.) To control contamination, Copernicus experimented with buttered bread. Amazingly, it seemed to work—and it tasted real fine too. Copernicus had a hit on his hands; buttered bread quickly became a dietary staple.

Certainly the story is fun, and it would be even better if we embellished it with a spinning cat. But you’ll excuse me if I think the whole thing is a crock. Are we really supposed to believe that he was the first person in the history of humanity to get the idea of putting bread and butter together? At the library today I consulted four biographies of Copernicus. Every one of them mentions the fact that Copernicus was in charge of Allenstein Castle when it was besieged for several months in 1520. Not one of them mentions a plague of any kind, not one of them mentions bread and butter. The book that went into the greatest detail said there were no soldiers, only castle servants.

Did Copernicus butter his bread? Undoubtedly, but so did half the population of Europe, I’d be willing to bet. Looking in the _Oxford English Dictionary_, under _buttered_, I find a citation from _The Treatyse of Fysshynge wyth an Angle_ (1496): “Browne breede tostyd wyth hony in lyknesse of a butteryd loof.” So I think we can safely say that people were butteryng their looves a good quarter century before Copernicus came along to show them the light.

I found several other references to the story on the Internet, some of which go so far as to imply that not only was he the first to put bread and butter together, he was the first person to make butter, period. That’s so insane, I won’t even dignify it with a rebutteral.

I couldn’t find anything butter to do, so I looked into this. [L.M. Boyd](http://www.dellarco.com/ontarget/framesets/trivia_frameset.html) also made the claim, and gave a few other details. The [Kharkov site](http://www.kharkov.net/home/english/welcome.htm) site makes the same claim.

What’s a loof? The Treatise of Fishing with an Angle was written by the nun Dame Juliana Berners in 1450, apparently.

Links to [Copernicus](http://www-groups.dcs.st-and.ac.uk/~history/Mathematicians/Copernicus.html), and [one of those sites that claim Copernicus invented butter](http://webofcommerce.com/userpages/TheUselessInfoPage.shtml).

[http://users.erols.com/tarasque/circular.htm](http://users.erols.com/tarasque/circular.htm) also says Copernicus was the first to butter his bread, but there are no supporting details.

I assumed _loof_ was “loaf”, but I suppose I may have been hasty in that assumption.

Didn’t Copernicus also invent milk? 😉

I agree with bibliophage that “inventing” buttered bread seems far too grandiose a claim. But I’m willing to admit the possibility (as described by L.M. Boyd, though I will refrain from commenting on L.M. Boyd’s habitual level of accuracy) that \<\<As commander of Allenstein castle during a 16th-century plague, he coated baked goods with a paste from churned milk in the hope it would purify the food. It didn’t. But the troops liked it. And everybody started wanting bread smeared with milk paste.\>\>  
However, it’s strange that this plague is not mentioned in any of the biographies consulted by bibliophage.
