Like everyone else on the wall, we fell to discussing what was happening and what might happen next.

"It's what Apollonides and the Timouchoi have been waiting for, praying for-the arrival of these ships from Pompey," said Hieronymus. "Unless the blockade can be broken, it's only a matter of time until the city falls. Even if Trebonius can't break through the walls, starvation will do his work for him. The famine has started. Do you know, there's even talk of cutting my rations. My rations, the scapegoat's portion! That shows you just how badly things are going." On the wall not far away a child was crying persistently, probably from hunger. Hieronymus sighed. "You saw the fleets sail out, Gordianus. How many Massilian galleys did you count?"

"Eighteen, plus a number of smaller craft."

"And Caesar's galleys, how many of those did you count?"

"Eighteen as well."

"And word has it that the fleet from Pompey numbers eighteen vessels as well. No doubt the priests will find some mystical significance in these multiples of eighteen! But what it means in practical terms is that the combined Massilian and Pompeian ships outnumber those of Caesar two to one. A clear advantage that any gambler would appreciate! Except, of course, that we've already seen what happens when Massilian galleys run up against those of Caesar, even when Caesar's ships were built in a rush and manned by infantry-disaster for Massilia! Granted, Pompey's reinforcements should provide at least an even match… but why did their commander anchor at Taurois? Why didn't he sail straight to Massilia if his intention is to break the blockade? There's something not quite right about this so-called 'relief force. Do you know what I think? I think they're headed for Spain to join with the Pompeian navy there, and this stop in the vicinity of Massilia is no more than a courtesy call, to sniff the wind and see which way it's blowing. Oh, they'll render assistance to Massilia-as long as it's not too much bother. But what sort of fight are they going to put up when they see the kind of warriors they're up against and their own blood begins to color the sea red? Say, what's this?" From his pouch he produced another stuffed date, peered at it distastefully, then flung it into the sea. I heard a little moan from Davus, followed by the sound of his stomach growling.

"You may be right, Hieronymus," I granted. "But you may be wrong. I can imagine another scenario. The fleets do battle and Caesar's ships are destroyed. Why not? Pompey has officers every bit as clever as Caesar's, and fighting men who are just as brave. The blockade is broken. The Timouchoi regain control of the sea and the coastline. Trading vessels can come and go. The city's food stores are replenished; the famine is lifted. As long as the walls hold firm, Massilia can hold off Trebonius indefinitely. Or perhaps do better than that: If these eighteen ships from Pompey arrive in Massilia filled with soldiers, Domitius and Apollonides might even dare to mount a counterattack against Trebonius. Trebonius could be forced to retreat, might even be destroyed. If Massilia can be made into a secure stronghold for Pompey, then Caesar's route back to Italy would be blocked. He could be trapped in Spain. Meanwhile, Pompey could muster his forces in Greece and Asia, sail back to Italy to take on Marc Antony-"

"'Might'…'Could'…'What if?'" Hieronymus shook his head. "In a universe ruled by capricious gods, anything is possible. But close your eyes. What do you hear? A child crying because it's hungry. Apollonides and the Timouchoi are responsible for that. When Caesar came knocking at our gates, they made a choice-and they chose wrongly. That was the moment to seek the gods' wisdom. Now it's too late…"

So we spent the long day, talking politics and warfare. When those subjects paled, we moved on to others-our favorite Greek dramas and Roman comedies, the relative merits of various philosophers, the prose of Caesar compared to that of Cicero. Hieronymus delighted in being argumentative. Whatever side I took, he took the other, and usually got the better of me. To his advantage, he seemed freshly versed on every subject, like a schoolboy immersed in learning. In his role as scapegoat, his every pleasure had been catered to; books, denied him in his years as a beggar, were among those pleasures. Massilia was famous for its academies and had no shortage of books. They had been delivered to the scapegoat's house by the wheelbarrow-full. He had stuffed himself with scrolls just as he had stuffed himself with food.

Hours passed. The chanting from the temples never ceased. Davus contributed little to the conversation, except for an occasional grumble from his stomach. I grew hungry too, if the stirring of appetite experienced by a well-fed man when he goes without food for a few hours is worthy of being called hunger. How did it compare to what the spectators along the battlements were experiencing? In a city under siege, noncombatants always receive smaller rations than their defenders. Women, children, and the old are the first victims of famine, and the least able to withstand it. To what level of daily, hourly craving had the spectators around us already descended? How much thinner would they be stretched, and how much longer would they have to endure it? Truly starving people will eat anything to fill their bellies-wood shavings, the stuffing from pillows, even dirt. Hunger robs its victims of every shred of dignity before it snuffs out their lives. And for those who survive starvation, pestilence inevitably follows. Then surrender to the besieger; then rape, plunder, slavery…

Like the spectators along the battlements, I anxiously watched the sea.

"Do you know the Fallacy of Enkekalymmenos?" Hieronymus suddenly asked.

Davus furrowed his brow at the long Greek word. "The Fallacy of the Veiled One," I translated.

"Yes. It goes something like this: `Can you recognize your mother?' `Of course.' `Do you recognize this veiled one?' `No.' `Yet this veiled one is your mother. Hence you can recognize your mother… and not recognize her.' "

I frowned. "Whatever made you think of that?"

"I'm not sure. Something I read recently. Aristotle, was it? Or Plato…?"

Davus looked thoughtful. "I don't see the point. You could put a veil over any woman and trick her child into not recognizing her. But-it wouldn't necessarily work." He raised an eyebrow and looked uncommonly shrewd. "What if the child recognized her perfume?"

"I suspect the veil is metaphorical, Davus."

"The fallacy is an epistemological allegory," Hieronymus interjected, but this, too, was Greek to Davus.

I cleared my throat, willing to debate the fallacy out of simple boredom. "How do we know what we know? How can we be sure of what we know? And what do we mean by `knowing,' anyway? Very often we say we `know' a person or a thing, when all we really mean is that we know what they look like. To truly know a thing, to know its essence, is knowledge of a different order."

Hieronymus shook his head. "But that's not the point of the fallacy. The point is that you can both know and not know at the same time. You can be in a state of knowledge and in a state of ignorance about the same subject simultaneously."

I shrugged. "That merely describes most people, about most subjects, most of the time. It seems to me-"

"Look!" said Davus. "Look there!"

A ship had appeared, sailing around the headland from the direction of Taurois. By the pale blue pennant atop its mast, we knew at once that it was a Massilian vessel.

A great cheer erupted from the spectators. Old men stamped their feet. Children let out shrill screams. Women who had stood for hours beneath the hot sun swooned and fainted. Although the ship was still too far off to appreciate the sight, many of the spectators waved their bits of cloth in the air.
