Marcella and Cornelia, nieces to Count Morosini and sisters to Julio, who is contracted to Laura Lucretia, a lady of quality, sister of Count Octavio, in order to avoid Marcella’s marriage with this nobleman, secretly leave Viterbo where they live, and accompanied only by their attendants, Petro and Philippa, come to Rome, and there pass for courtezans under the names of Euphemia and Silvianetta. Their beauty wins them great renown in the gay world, and Sir Harry Fillamour, who loves Marcella, and Frank Galliard, two English travellers, are keenly attracted by this reputation. Sir Harry, however, is anxious for matrimony, Galliard for an intrigue. Marcella in her turn is already enamoured of Fillamour whom she has met at Viterbo. Morosini and Octavio follow the fugitives to Rome, whilst Laura Lucretia, who loves Galliard, disguises herself in male attire and takes a house on the Corso next door to the supposed courtezans. Fillamour and Galliard encounter the two ladies in the gardens of the Villa Medici, and Fillamour takes Marcella for a courtezan, whilst Galliard engages with Cornelia. Octavio passing with his followers spies and attacks his rival. A general mêlée ensues. Julio, who has not seen his family for seven years, next appears, having taken Cornelia for a cyprian and followed her from St. Peter’s. Marcella, in boy’s attire, then gives Fillamour a letter from herself, signed under her own name, making an appointment for that night; but at the same time Galliard, claiming a former promise, drags his friend off to visit Euphemia. The intrigue is complicated by the ridiculous amours of two foolish travellers, Sir Signal Buffoon and Mr. Tickletext, a puritan divine, his tutor. These, unknown to each other, make assignations with the two bona robas by means of Petro, who dupes them thoroughly by his clever tricks, and pockets their money. Whilst Galliard and Sir Harry are serenading the ladies, Octavio, Julio and their bravos attack them. After the scuffle Laura Lucretia coming from her house leads in Julio, mistaking him for Galliard, and he her for Silvianetta. Next Sir Harry and Galliard arrive in safety at the sisters’ house, and Marcella, as a courtezan, tempts her lover, who, however, refuses to yield and leaves her, to her secret joy. Tickletext has been placed by Petro in bed to await, as he supposes, Silvianetta, when Galliard in error entering the room in the dark gropes his way to the bed and finding a man, closes with him. The tutor escapes, and Cornelia coming in in the course of her wooing by Galliard informs him she is not really a courtezan as he supposed. In anger her gallant departs. Whilst he is telling Sir Harry this tale Cornelia, dressed as a page, follows him and delivers Fillamour a challenge as from Marcella’s brother, Julio, summoning him to the Piazza di Spagna. Julio himself, newly come from Laura Lucretia, meeting Galliard relates to him how he passed the night with Silvianetta, which
