I have found several sources (Wikipedia, Eats Shoots & Leaves) that claim Erasmus was the first person to use parentheses (also known as brackets). He supposedly called them lunulae (because they looked like moons). But I can't find any source citations.
Can anyone provide more information about this supposed fact? In which book did Erasmus first use them? What year was the book published?
The reason I want to know is that Erasmus lived (and died) in the town where I live (Basel, Switzerland). I am trying to determine if parentheses were invented here in Basel.
