The Norton Shakespeare (1997)
Indeed, if Puck takes mischievous delight in the discord he has helped to sow among the four young lovers … he is not the originator of that discord, and he is the indispensable agent for setting things right. In his role as both mischief maker and matchmaker, Puck resembles the crafty slave in comedies by Latin playwrights Plautus and Terence, a stock character who sometimes seems to enjoy and contribute to the plot’s tangles but who manages in the end to remove the obstacles that stand in the way of the young lovers.
