The Comedy of Errors is based on two plays by Plautus, The Menaechmi and Amphitruo.

Some famous writers of Latin comedies include Plautus, Terence, and Seneca. Plautus, who is considered the father of Roman comedy, wrote popular works such as "The Menaechmi" and "Pseudolus." Terence was known for his refined style and moral themes in plays like "The Brothers" and "The Eunuch." Seneca, a philosopher and playwright, wrote tragedies but also dabbled in comedies like "The Double Indemnity."

Shakespeare got his story ideas from a number of different writers. Two major ones are Raphael Holinshed, whose Chronicles of England, Scotland and Ireland provided the storylines for all of the history plays and also for Macbeth, eleven plays in all, and Plutarch, whose Lives of the Greeks and Romans provided the storylines for Julius Caesar, Antony and Cleopatra and Coriolanus. The rest were one-offs: As You Like It came from Lodge's Rosalind; Romeo and Juliet from Brooke's Romeus and Juliet; King Lear from the old anonymous Queen's Men play King Leir; The Comedy of Errors from Plautus's Menaechmi; etc. etc. Shakespeare also occasionally created his own plot, particularly in The Merry Wives of Windsor, The Tempest and A Midsummer Night's Dream
