That was the final prototype not only for the quotation mark, but also for the comma.
It is believed to have originated in Roman times, circa 100 BC. But this has been substantiated to be incorrect.
Later instances point to the American Indian and southern Mexican tribes as a tool for pounding corn into mash for breads, and for the Mexicans, a way to make tacos to bend.
Even though the comma is still used today, it is believed that it's form was lost for many years up until present day, where it is still commonly forgotten about altogether.
Shortly before 1984 its form was almost rediscovered by an orange cat by the name of Garfield, who had incorporated beans into the design, and referred to it as a whack bonk. Please see below for authentication.
Surprisingly the whack bonk was found to date back to caveman times, when it was actually used not to separate words so much as it was used to separate other men from their women as well as their dinner.
