Mercator, or The Merchant, is a Latin comedic play for the early Roman theatre by Titus Maccius Plautus. It is based on the Greek play Emporos (the Merchant) by the Greek comedy playwright Philemon. It is believed to be among Plautus's first plays, possibly written around 206 BC. The central conflict involves a father who falls in love with a slave girl who is, unbeknownst to the father, his son's lover.

Plot
The play takes place in a street in Athens. In the back wall of the stage there are two houses, that of Demipho and his son Charinus, and that of his friend Lysimachus and his son Eutychus. There is a shrine or altar of Apollo near Lysimachus's house.
Prologue
Charinus explains that he had taken after his father's example and decided to become a merchant. He had much success in Rhodes and there fell in love with a slave woman named Pasicompsa. He purchased Pasicompsa and brought her with him to his home in Athens where he now ponders how to prevent his father from discovering his love.
Act I
Acanthio runs to Charinus from the harbor to deliver news that Demipho has been to the ship and seen Pasicompsa. To cover for Charinus, Acanthio had convinced Demipho that Charinus had purchased Pasicompsa to serve as a maid for Charinus's mother. He further tells Charinus that Demipho was flirting with Pasicompsa. Charinus decides he must go to the harbor at once.
Act II
Returning from the harbor, Demipho enters and claims that he has had a dream in which he entrusted a prize goat to his monkey friend, but the monkey lost the goat to a younger goat. He admits to his neighbor Lysimachus that he has fallen in love and feels youthful. Lysimachus leaves and Charinus enters, lamenting his predicament. Demipho then tells Charinus that Pasicompsa is too fine to be a maid and instead insists Pasicompsa be sold. The two begin a bidding war, each claiming to represent imaginary clients. Demipho rejects his son's offers and turns Charinus away from the harbor. When Charinus exits, Demipho reveals his plan to have Lysimachus purchase Pasicompsa on Demipho's behalf. Separately, Charinus sends Eutychus to purchase Pasicompsa himself.
Act III
Lysimachus buys Pasicompsa and is bringing her to Lysimachus's home. He tells her he bought her on behalf of her own master, and Pasicompsa is pleased, believing Lysimachus to mean Charinus. After they exit into Lysimachus's house, Demipho enters and attempts to justify what he believes he has earned with age. Lysimachus returns to Demipho and tells him he must find Pasicompsa elsewhere to stay before Dorippa returns from the countryside. For the time being, the two exit to find a cook for a feast to be held that night. Shortly after, Eutychus tells Charinus that he was too late and Pasicompsa was sold to an unknown buyer. Heartbroken, Charinus decides he will leave Athens, but Eutychus becomes determined to find Pasicompsa.
Act IV
Dorippa returns home from the countryside earlier than expected, and she and Syra (whose name is meant to imply her Syrian ethnicity) discover Pasicompsa in the house, believing her to be Lysimachus's mistress. Lysimachus returns home and tries to explain to his wife that he is only looking after Pasicompsa temporarily, but when the cook hired for that night's feast arrives, Dorippa becomes only more sure of her suspicions and exits into her house crying. Lysimachus dismisses the cook and follows after his wife. Eutychus returns home to find Syra outside, who urges him inside to see his father's mistress. Syra laments the inequalities between the unfaithfulness of men and women.
Act V
Eutychus finds Charinus just as Charinus is about to leave Athens and tells him that he has found Pasicompsa in Eutychus's own home. Charinus exits into the home, and Eutychus remains outside to confront Lysimachus and Demipho. He tells them Pasicompsa was really Charinus's lover and that Demipho should be ashamed for trying to take her for himself. He proposes a law that old men should not interfere in the passionate love of young men, and the three exit into Lysimachus's house.
