VI. The Bacchides are two twin sisters, one of whom is beloved by her sister’s lover. He does not know that there are two, and, misled by the similarity of the name, thinks himself betrayed. Hence arise amusing situations and incidents, but at length an éclaircissement takes place. VII. The Captivi, for its style, sentiments, moral, and the structure of the plot, is incomparably the best comedy of Plautus. In a war between the Ætolians and Eleians, Philopolemus, an Ætolian, the son of Hegio, is taken prisoner, whilst Philocrates is captured by the Ætolians. Philocrates and his slave Tyndarus are purchased by Hegio, with a view to recover his son by an exchange of prisoners. The master and slave, however, agree to change places; and thus Philocrates is sent back to his country, valued only as a slave. Hegio discovers the trick, and condemns Tyndarus to fetters and hard labour. Philocrates, however, returns, and brings back Philopolemus with him, and it also turns out that Tyndarus is a son of Hegio whom he had lost in his infancy. VIII. The Curculio derives its name from a parasite, who is the hero, and who acts his part in a plot full of fraud and forgery; the only satisfactory point in the comedy being the deserved punishment of an infamous pander. IX. In the Cistellaria, Demipho, a Lemnian, promises his daughter to Alcesimarchus, who is in love with Silenium. The young lady has fallen into the hands of a courtesan, who endeavours to force her into a vicious course of life; she, however, steadily refuses; and it is at length discovered, by means of a box of toys (cistella,) that she is the illegitimate daughter of Demipho, and had been exposed as an infant. Her virtue is rewarded by her being happily married to her lover. X. The Epidicus was evidently a favourite play with the author, for he makes one of the characters in another comedy say that he loves it as dearly as himself.[184] The plot turns on the common story of a lost child recognised. The intrigue, which is remarkably clever, is managed by Epidicus, a cunning slave, who gives the name to the play. XI. The Mostellaria is exceedingly lively and amusing. A young man, in his father’s absence, makes the paternal mansion a scene of noisy and extravagant revelry. In the midst of it the father returns, and in order to prevent discovery, a slave persuades him that the house is haunted. When he discovers the trick he is very angry, but ultimately pardons both his son and the slave. The name is derived from Mostellum, the diminutive of Monstrum, a prodigy, or supernatural visitor. XII. The Menæchmi is a Comedy of Errors, arising out of the exact likeness between two brothers, one of whom was stolen in infancy, and the other wanders in search of him, and at last finds him in great affluence at Epidamnus. It furnished the plot to Shakspeare’s play, and likewise to the comedy of Regnard, which bears the name of the original.
