Ignoramus is a college farce, a 1615 academic play by George Ruggle. Written in Latin (with passages in English and French), it was arguably the most famous and influential academic play of English Renaissance drama. Ruggle based his play on La Trappolaria (1596), an Italian comedy by Giambattista della Porta (which in turn borrows from the Pseudolus of Plautus).
In Latin, , the first-person plural present active indicative of (“I do not know”, “I am unacquainted with”, “I am ignorant of”), literally means “we are ignorant of” or “we do not know”. The term acquired its English meaning of an ignorant person or dunce as a consequence of Ruggle's play.
The play was first produced in Clare College, Cambridge on Wednesday, March 8, 1615, as part of the program of entertainments for a visit by King James I. James enjoyed the play so much that he returned to Cambridge to see it again on Saturday, May 13 of that year. Contemporary John Chamberlain reported that "the play was full of mirth and variety with many excellent actors, but more than half spoiled by its extreme length of six hours.
Ignoramus was entered into the Stationers' Register on April 18, 1615, and was published later that year by the bookseller Walter Burre. Two subsequent editions were issued in 1630, and other editions followed in 1658, 1659, 1668, 1707, 1731, 1736, 1737, and after. John Sidney Hawkins issued an elaborately-edited text in 1787.
