Ambassador Menandros, Easterner though he was, had apparently never met a Hebrew before, and needed to have bar-Heap explained to him. “They are a small tribe of desert folk who settled in Aegyptus long ago,” Faustus told him. “Scatterings of them live all over the Empire by now. I dare say you would find a few in Constantinopolis. They are shrewd, determined, rather argumentative people, who don’t always have the highest respect for the law, except for the laws of their own tribe, by which they abide under all circumstances in the most fanatic way. I understand they have no belief in the gods, for instance, and only the most grudging allegiance to the Emperor.”
“No belief in the gods?” said Menandros. “None at all?”
“Not that I can see,” said Faustus.
“Well, they do have some god of their own,” Maximilianus put in. “But no one may ever see him, and they make no statues of him, and he has laid down a whole lot of absurd laws about what they can eat, and so forth. Bar-Heap will probably tell you all the details, if you ask him. Or perhaps he won’t. Like all his kind, he’s a prickly, unpredictable sort.”
Faustus had advised the ambassador that it would be best if they dressed simply for the outing, nothing that might indicate their rank. Menandros’s wardrobe, of course, ran largely to luxurious silken robes and other such Eastern splendiferousness, but Faustus had provided a plain woolen toga for him that had no stripes of rank on it. Menandros appeared to know how to drape the garment properly around himself. Maximilianus Caesar, who as the son of the reigning Emperor was entitled to wear a toga bedecked with a purple stripe and strands of golden thread, wore an unmarked one also. So did Faustus, although, since he too was the descendant of an Emperor, he was permitted the purple stripe as well. Even so, no one down below was likely to mistake them for anything other than what they were, Romans of the highest class. But it was never a good idea to flaunt patrician airs too ostentatiously in the subterranean world of Roma.
The entrance that the Hebrew had chosen for them was at the edge of the teeming quarter known as the Subura, which lay east of the Forum in the valley between the Viminal and Esquiline Hills. Here, in a district marked by stench and squalor and deafening hubbub, where the common folk of Roma lived jammed elbow to elbow in shoddy buildings four and five stories high and screeching carts proceeded with much difficulty through narrow, winding streets, the Emperor Titus Gallius had begun carving, about the year 980, an underground refuge in which the citizens of Roma could take shelter if the unruly Goths, then massing in the north, should break through Roma’s defenses and enter the city.
The Goths, as it happened, were routed long before they got anywhere near the capital. But by then Titus Gallius had built a complex network of passageways under the Subura, and he and his successors went on enlarging it for decades, sending tentacles out in all directions, creating linkages to the existing labyrinthine chain of underground galleries and tunnels and chambers that Romans had been constructing here and there about the city for a thousand years.
And by now that Underworld was a city beneath the city, an entity unto itself down there in the dank and humid darkness. The portals of Titus Gallius lay before them, two ornate stone arches like the gaping jaws of a giant mouth, rising in the middle of the street where Imperial forces centuries ago had cleared away a block of ancient hovels on both sides to make room for the entrance plaza. The opening into the Underground was wide enough to allow three wagons to pass at the same time. A ramp of well-worn brown brick led downward into the depths.
“Here are your lanterns,” bar-Heap said, lighting them and handing them around. “Remember to hold them high, to keep them from going out. The air is heavier down by your knees and will smother the flame.”
As they embarked on the ramp the Caesar took the position at the front of the group; Faustus positioned himself next to the Greek; bar-Heap brought up the rear. Menandros had been taken aback to learn that they would be traveling by foot, but Faustus had explained that using porter-born litters would be inconvenient in the tight passageways of the crowded world below. They would not even be accompanied by servants. The Greek seemed delighted to hear that. He was truly slumming today, that was clear. He wanted to travel through the Underworld as an ordinary Roman would, to get right down into all its muck and filth and danger.
Even this early in the day the ramp was crowded, both in the upward and downward directions, a quick, jostling throng. Ahead, all was cloaked in a palpable gloom. Going into the Underworld had always seemed to Faustus like entering the lair of some enormous creature. He was enveloped once again now by the thick, fierce darkness, cool, spicy. He savored its embrace. How often had he and Caesar entered here in search of a night’s strange entertainment, and how many times they had found it!
Quickly his eyes began to adapt to the dim murky gleam of the lanterns. By the dull light of distant torches he could see the long ranges of far-off vaults running off on every side. The descent had quickly leveled out into the broad vestibule. Gusts of fetid underground air blew toward them, bearing a host of odors: smoke, sweat, mildew, the smell of animal bodies. It was very busy here, long lines of people and beasts of burden coming and going out of a dozen directions. The wide avenue known as the Via Subterranea stretched before them, and myriad narrower subsidiary passages branched off to right and left. Faustus saw once more the familiar piers and arches and bays, the curving walls of warm golden brick, the heavy rock-hewn pillars and the innumerable alcoves behind them. At once the darkness of this shadowy world seemed less oppressive.
He glanced down at the Greek. Menandros’s soft features were alive with excitement. His nostrils were quivering, his lips were drawn back. His expression was like that of a small child who was being taken to the gladiatorial games for the first time. He almost seemed like a child among the three tall men, too, a flimsy, diminutive figure alongside long-limbed Maximilianus and sturdy, deep-chested bar-Heap and fleshy, bulky Faustus.
“What is that?” Menandros asked, pointing to the enormous marble relief of a bearded head, cemented into the wall just ahead of them. From above came a spike of light from one of the openings that pierced the vaulted roof, admitting a white beam that lit up the carved features with an eerie nimbus.
“He is a god,” said bar-Heap from behind, with a tincture of contempt in his voice. “An Emperor put him up there, many years ago. Perhaps he is one of yours, or perhaps one from Syria. We call him Jupiter of the Caverns.” The Hebrew raised his lantern far over his head to provide an additional burst of illumination for that powerful profile, the great staring eye, the huge all-hearing ear, the ominously parted lips, the massive coiling stone beard thicker even than his own. Everything above the eye was gone, and below the beard there was nothing also: it was a single colossal fragment that looked unthinkably ancient, a brooding relic of some great former age. “Hail, Jupiter!” bar-Heap said in a resonant tone, and laughed. But Menandros paused to examine the immense somber face, and to take note of the marble altar, worn smooth by adoring hands and luminous in the reflected light of candles mounted along its rim, just below it. The charred bones of sacrifices, recent ones, lay in a niche in its side.
