Chilo infiltrates the Christian community to find Lygia

Chilo infiltrates the Christian community to find Lygia by converting a remembered fish traced in sand into a lead, then presenting himself as a believer to gain access to the people who may know where she is hidden. His search advances through observation, a deliberately staged conversion, and acts of aid that earn him entry to Christian networks; the same investigation exposes the difference between the community’s ethic of mutual help and Chilo’s continuing pursuit of a paid reward.

The Fish as a Clue

Chilo’s plan begins with a question about how he might recognize the religion shared, he suspects, by Pomponia and Lygia. He asks whether Vinicius has seen a token, amulet, offering, or private sign passing between them. Vinicius recalls that Lygia once drew a fish on the sand. Chilo immediately identifies her as a Christian and concludes that Christians carried her away. The unremarkable mark becomes, for him, an investigative key: rather than search only by name or appearance, he can test how people respond to the sign.

He tells Vinicius and Petronius that he has become a Christian only the day before, claiming that the fish itself made him one. The claim is not a settled confession of faith but an instrument for entering the group. Chilo frankly describes his method as adopting whatever belief serves his present need, while also joking that Mercury should receive two heifers if he helps locate Lygia. His shifting professions of belief expose the opportunism beneath the role he performs.

Earning Access Through Aid

Chilo says he has tested the fish in streets and workplaces, moving through wine shops, bakeries, butcher shops, oil sellers, fishermen, laundries, cheap kitchens, and cemeteries. After days without useful information, he encounters an old slave weeping at a fountain. The man explains that he had saved money to redeem his son, but the son’s owner accepted the payment and kept him enslaved. Chilo draws the fish in the water; the old man recognizes the sign and says his hope is in Christ. That exchange opens a path into the Christian community.

The old man tells Chilo that Christians work among the people unloading stones brought by barge on the Tiber and carrying them into the city at night. His own son is among the workers. Chilo gives him the money needed to redeem the son, then asks to be introduced to fellow Christians and the community’s elders. The generosity is useful to both parties: the father receives the means to free his son, while Chilo gains a contact who can lead him to prayer gatherings. Chilo expects Vinicius to reimburse him at a profit, so the assistance also remains part of a commercial bargain.

Chilo recounts the episode to his employers as evidence of the value of his approach. He says he has visited many kinds of places, lost nearly a hundred ases playing mora, and spent days walking in search of anyone who might recognize the fish. He asks that Eunice keep quiet about his presence and that Vinicius spread a false pretext for his movements, claiming Chilo sells an ointment for racehorses. His request shows that infiltration depends not only on apparent sympathy but on controlling what outsiders know about his purpose.

From Contact to Christian Gatherings

Vinicius secretly follows Chilo and witnesses the encounter with the old man and his son. At the riverside work site, he sees Chilo give the father a purse; the old man prays with raised hands, and others gather around. Chilo makes a sign of the cross, and the people kneel. The scene independently confirms that the aid has brought Chilo into contact with Christians, even as Vinicius restrains himself from interrupting the search by offering a larger reward directly.

Chilo reports that Christians regard him as one of their own, in part because he redeemed the son of Euricius. He has entered two more prayer gatherings, where he watches the women especially for someone resembling Lygia. The Christians are numerous, cautious, and not all acquainted with one another; Chilo therefore says he must approach the elders, called presbyters, patiently rather than provoke suspicion through haste. He learns that meetings take place outside the city as well as in empty houses and sand-pits, where Christians pray, sing hymns, and share meals. The variety of meeting places explains why access to one group does not immediately reveal Lygia’s whereabouts.

Chilo’s account also complicates the suspicions surrounding the Christians. He tells Vinicius that he has not seen them indulge in the crimes popularly attributed to them, such as poisoning water or harming children. As far as his observations go, their religion enjoins forgiveness rather than crime. His report does not end his mercenary search, but it records a growing discrepancy between the community he encounters and the rumors used to vilify it.

The Search Narrows

After a long interval, Chilo returns with news that Lygia is among the Christians and that he has encountered Glaucus, an older man from his journey from Naples to Rome. Chilo had previously told Vinicius that robbers attacked Glaucus’s party and that he lost two fingers defending him. Now he claims Glaucus survived and accuses him of complicity in the robbery. Vinicius, concerned chiefly that Glaucus may obstruct the search, agrees to Chilo’s proposed payment for hiring men to kill him. The episode shows how Chilo’s access to the community becomes entangled with his attempt to remove a person who might expose him or impede his plans.

Although Chilo has not yet found Lygia, he knows that Ursus works near the Emporium for a miller named Demas. He has not pressed Ursus for the hiding place, reasoning that direct questioning might alert the protector and force Lygia to be moved. Instead, he offers Vinicius a more promising lead: Lygia will probably attend a Christian gathering at Ostrianum, an old underground cemetery between the Via Salaria and the Via Nomentana, where Peter is expected to teach and baptize. Chilo’s restraint has advanced the search without yet disclosing the exact refuge; his information allows Vinicius to pursue the next gathering himself.

Performance, Patronage, and Risk

Chilo’s infiltration operates through more than disguise. He asks Vinicius and Petronius for advance money, describes the costs of his search, and presents the redemption of the enslaved son as both proof of his usefulness and a debt the wealthy Vinicius should repay. Vinicius, meanwhile, uses his own resources and connections in pursuit of Lygia, while Petronius warns Chilo that the promised reward depends on producing her hiding place. Their arrangement turns the search into a chain of patronage: money purchases effort and information, but Chilo controls the access that the patrons cannot obtain directly.

The episode’s irony lies in the fact that Chilo gains entry by performing a faith whose adherents respond to the suffering of a stranger with practical aid. Their network gives him the contacts he needs, yet the aid he witnesses also gives him evidence against the hostile stories circulating about them. He remains intent on locating Lygia for Vinicius, and his false conversion does not erase the selfish calculation behind his methods. By the time he identifies the likely gathering at Ostrianum, however, his account has made the Christian community more than a hiding place: it is a network of worship, work, mutual assistance, and guarded trust that an outsider can enter only by convincing its members that he belongs.
