alt Hacker NewsWell, I mean you find lots of wonky sculptures and reliefs in medieval art but people in Europe still made some really stunning pieces of art, e.g. see The Lady and the Unicorn (https://en.wikipedia.org/wiki/The_Lady_and_the_Unicorn), or the Choir Screen at the Amiens Cathedral (https://en.wikipedia.org/wiki/Amiens_Cathedral#The_Choir_scr....)) and so on. So it's kind of a sweeping generalisation to say that "medieval art generally sucked".
Mmm both of those are from 1400s and OP do limit it to 1300. And that 1300 limit is for good reason. Renaissance is usually dated after 1453 and that's when European art quality exploded. So yeah, those examples instead prove OP's statement.
