Where 1517 fits
Why 1517 is special
The theses objected to the sale of indulgences and were written in Latin for scholarly debate rather than mass circulation. Printing turned them into something else within months. The often-repeated image of Luther nailing them to the Wittenberg church door is recorded only after his death and remains disputed.
