I'm in ur manuscript, making a mess.

Emir O. Filipovic

For cat owners, the scene is all too familiar: You sit down to finally (finally!) get some work done, and along comes kitty, here to stroll across your keyboard.

Now, via medievalist Emir O. Filipovic, evidence that cats have been up to this same mischief for six centuries: inky pawprints, gracing a page of the 13th volume of "Lettere e commissioni di Levante," which collated copies of letters and instructions that the Dubrovnik/Ragusan government sent to its merchants and envoys throughout southeastern Europe (Bosnia, Serbia, Croatia etc.), according to Filipovic -- sort of a 15th-century Federal Register. The particular document that the cat got its paws on dates to March 11th, 1445.

More than just a silly reminder that cats never change (surprise!), the pawprints flicker through time to describe to us a little something about the person who once lived and who set those words to that page. As Kate Beaton described it on Twitter:

the best part is that is makes the writer of that manuscript seem more real, with his little cat that he has to take care of, his daily life -- Kate Beaton (@beatonna) February 19, 2013
