percontation

The percontation point is analogous to the Irony mark, but these are very rarely seen.

In the 1580s, Henry Denham introduced a rhetorical question mark or percontation point which resembles a reversed question mark.

Among the oldest and frequently attested are the percontation point-furthered by Henry Denham in the 1580s-and the irony mark-furthered by Alcanter de Brahm in the 19th century.

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.

This percontation point (؟), later also referred to as a rhetorical question mark, was invented by Henry Denham in the 1580s and was used at the end of a question that does not require an answer-a rhetorical question.

Among the oldest and frequently attested are the percontation point invented by English printer Henry Denham in the 1580s, and the irony mark, used by Marcellin Jobard in an article dated June 11, 1841 and commented in a 1842 report.
