I stepped into the inn. The vestibule was dark, but the doorway to the tavern framed the soft glow of a single lamp. Gnaeus must have lit the lamp. I imagined him standing in the room, alone amid the ghosts of the slain. At any moment, soldiers from the garrison would arrive to arrest him for his complicity in the murders. I had no intention of warning him, but something compelled me to step into the tavern.

Half in light, half in shadow, Gnaeus hung from a rope secured to a beam in the ceiling. His lifeless body still swayed slightly, as if he had committed the act only moments before. Ismene had told me he would be dead before nightfall.

The next day, Menenius allowed us to leave. He even arranged for our transportation across the isthmus. Two soldiers drove us in a wagon, and seemed glad for the excursion.

At Cenchrea, we found a ship to take us to Piraeus, and continued on our journey.

As the Isthmus of Corinth receded in the distance, I wondered if the magic of Ismene had truly motivated all the bloodshed and havoc of the last few days, with no one aware of the full truth except the witch herself. If that were the case, how many times already in my life had I been the unknowing agent of unseen powers, and when would I next fall under the spell of such sorcery?

I shivered at the thought, and hoped never to encounter Ismene again.

THE MONUMENTAL GAUL

(The Colossus of Rhodes)

“Mark my words, Gordianus, that young fellow is destined to become one of the shining intellects of the age, a beacon of wisdom and learning.”

This was quite a compliment, coming from Antipater. He was speaking of our host in Rhodes, a man named Posidonius. Considering the flecks of gray at his temples, I wouldn’t have called Posidonius a “young fellow,” but then, I was only eighteen. To my old tutor, I suppose Posidonius seemed quite youthful. He was certainly energetic, constantly jumping up from his chair to fetch a scroll to elucidate some point, or pacing to and fro across the garden and gesticulating as he recounted some tale about his travels in Gaul, from which he had only recently returned.

Posidonius was not just a scholar and a scientist; he was an intrepid explorer whose quest for knowledge had taken him to many lands. His travels had begun with a stop in Rome several years ago; that was when he first met Antipater, and so impressed the poet that the two exchanged many letters as Posidonius traveled to Africa and Spain, and then to Gaul, where he spent a number of years living among the natives and observing their strange customs. Posidonius had at last returned to Rhodes, just in time for Antipater and me to take advantage of his hospitality.

“Here, this is an example of what I was talking about,” said Posidonius, returning to the garden. He carried a long knife, holding it forth on his palms so that we could observe the silver hilt decorated with elaborate whorls and weird animal faces. “This is a ceremonial knife that was actually used by a Gallic Druid in a blood ritual to predict the future. I witnessed the sacrifice with my own eyes. The victim was a captured warrior from another tribe. The poor fellow was made to stand with his hands bound behind his back while two strong men held him fast, then the chief Druid used this very knife to stab him, just above the diaphragm. As the victim convulsed, they released him and carefully observed in what direction he fell, how many times he kicked out his legs, and what sort of pattern his spurting blood made on the ground—and from those observations, the Druids were able to conclude that their chieftain’s infant son would be free of the fever afflicting him within three days.”

“And did the child recover?” asked Antipater.

“Yes, he did. Of course, most fevers, unless they kill the patient, are over within three days, but the chieftain was nonetheless much comforted by the prediction, and generously rewarded the Druids when it came true.”

“Predicting the future from blood spatters—it seems rather far-fetched,” I ventured to say.

Posidonius raised an eyebrow. “If a Roman augur may presume to read the will of the gods by watching a chicken peck at some scattered grain, why should a Druid not be able to do so by studying a pattern of blood?” From his blank expression, I couldn’t tell whether he was being serious or sardonic.

Since leaving Rome on my travels with Antipater, moving among Greeks in the Greek-speaking part of Rome’s empire, I had learned that it was not uncommon for a young Roman to be subjected to subtle ridicule, practical jokes, and even, on occasion, outright displays of hostility. The city of Rhodes and the island of the same name were not yet part of Rome’s empire, having maintained independence even as neighboring islands and much of the mainland of Asia were subjected to Roman rule, and in Rhodes I had not encountered quite as much anti-Roman sentiment as elsewhere. Still, I was not sure what to make of the tone Posidonius often took when addressing me, as if he were making a joke that I was too dull to perceive. Perhaps he simply spoke to me the way he spoke to the students who attended his academy.

It had been ten days since Antipater and I arrived in Rhodes. The ship carrying us had entered the harbor at dusk—and had been one of the last ships to do so, for winter was coming on, and with it the unpredictable gales and storms that put an end to the sailing season.

As we sailed past a long mole that projected into the water, I eagerly looked to see what every newcomer to Rhodes is curious to see: the remains of the fallen bronze Colossus, deemed one of the Seven Wonders of the World despite its ruined state. By the uncertain light I had caught glimpses of the huge and grotesquely disconnected remains that lay scattered on the mole—two feet still firmly connected to a high pedestal, a forearm that lay half-submerged amid the lapping waves, and most disconcerting, because one enormous eye seemed to be staring straight back at me, a gigantic head that lay on its side. Where the other eye should have been there was a gaping hole in the bronze. Perhaps it had been damaged when the giant statue tumbled to the ground, felled by an earthquake 135 years ago.

By the time the ship docked and the harbor officials boarded to inspect our travel documents, it had been too late to take a closer look at the Colossus. Instead, Antipater and I headed directly to the house of Posidonius, which was located in the city’s acropolis district, a considerable distance from the harbor.

It was Antipater’s plan that we would spend the winter in Rhodes. The large, luxuriously appointed house of Posidonius certainly seemed a comfortable place to do so. Weary of traveling, Antipater seemed content to venture no farther each day than the garden, where he liked to sit and bask whenever a bit of weak sunshine broke through the clouds, or to converse with our host, who joined us whenever a break in his teaching schedule allowed. When Posidonius was absent, Antipater perused our host’s large collection of scrolls and travel memorabilia. In the evenings we dined with Posidonius in a charming room that opened onto the garden, usually joined by one or two of his more promising students, or by some person of note in the city. Rhodes was known not just for scholars, but for its athletes, merchants, and artists.

Under normal circumstances, Antipater would no doubt have been asked to address the students at the academy, but Posidonius understood that the poet was traveling incognito. Posidonius told us that he himself had occasionally assumed false identities during his travels, and he accepted Antipater’s need for discretion without question. Antipater was always introduced not as a famous poet, but as the humble tutor Zoticus of Zeugma, traveling companion of young Gordianus of Rome.
