Square academic cap - Wikipedia, the free encyclopedia |
 | | The square academic cap, very commonly called a mortarboard (from the French mortier, a type of toque), is an item of academic headgear consisting of a horizontal square board fixed upon a skull-cap, with a tassel, or liripipe, attached to the centre. |
 | | The mortarboard is believed to have evolved from the biretta, a similar-looking hat worn by Christian clergy. |
 | | Until the second half of the 20th century, mortarboards were often worn by schoolteachers, and the hat remains an icon of the teaching profession. |
