What does Mortar Board symbolize?

Mortarboard caps are thought to have been created in the 15th century, as part of an evolution from a hat type known as a birettas which was used by Catholic clerics and professors. The distinctive square shape of a mortarboard is believed to signify a book, chosen in recognition of scholarly achievements.

What is the origin of mortar board?

The mortarboard is generally believed by scholars to have developed from the biretta, a similar-looking hat worn by Roman Catholic (and High Church Anglican) clergy. The biretta itself may have been a development of the Roman pileus quadratus, a type of skullcap with superposed square and tump (meaning small mound).
