Bayeux Tapestry - not a tapestry, but at 230 feet it can call itself whatever it wants

The Bayeux Tapestry is not a tapestry and was not created in Bayeux. A tapestry is a textile that has the image woven into it whereas the Bayeux Tapestry is actually an embroidered cloth. It was originally created in England.

Bishop Odo had a long graphical story to tell, but was constrained by the total lack of a comic book industry in the 1070's. The text is written in Latin, so it would be a pretty niche comic anyway, but being unable to read this thing is reasonably realistic given that most people were probably illiterate in the early, mid, and late 1000's anyway.

This not-tapestry was first referenced in a 1476 inventory of Bayeux Cathedral. It was later referenced in the Simpsons couch gag for E Pluribus Wiggum (2008). In 2012 there was another Simpsons episode Moe Goes from Rags to Riches which is about a similar very long tapestry which eventually became Moe's bar rag. The real one fared better. It appears to be missing up to 21 feet at the end, but the rest survived in good condition and is currently an exhibit in a museum in Bayeux.
