Question mark
The rhetorical question mark or percontation point was invented by Henry Denham in the 1580s and was used at the end of a rhetorical question; however, its use died out in the 17th century. It was later revived in modern-day society by Matt DiRoberto. It was the reverse of an ordinary question mark, so that instead of the main opening pointing back into the sentence, it opened away from it. This character can be represented using the reversed question mark (⸮) found in Unicode as U+2E2E. The percontation point is analogous to the irony mark, but those are even more rarely seen.
Quotation marks in English
Quotation marks were first cut in metal type during the middle of the sixteenth century, and were used copiously by some printers by the seventeenth. In some Baroque and Romantic-period books, they would be repeated at the beginning of every line of a long quotation. When this practice was abandoned, the empty margin remained, leaving the modern form of indented block quotation.
