“Glad you like it,” Onetor said. “I wouldn’t want you to buy without knowing what you’re gessing.”

“I can see why,” Sostratos said, a little ruefully, or maybe more than a little. He’d known truffles were expensive. Now he understood the reason. He wondered just how much Onetor would try to squeeze out of him.

“Do you think you’d be interested in taking my goods to Athens?” the truffle-seller asked.

“I’m sure I’d be interested,” Sostratos answered. “Whether I can afford them is likely to be a different question.”

Onetor grinned at him. He could grin; he wasn’t nearly so gloomy as Onesimos. He said, “For top grade, I charge three simes the truffles’ weight in silver. I don’t haggle. If you want them, that’s what you’ll pay. You won’t find anybody cheaper in Mytilene, and you won’t find anybody with better goods.”

Any trader could say that. From the frequency with which Onetor’s name had come up in the agora, he was the leading truffle dealer in town. Sostratos supposed he could charge six or eight drakhmai in Athens for each drakhma’s weight of truffles. But there might be a better way. “Do you have to have silver?” he asked. “Or can we trade goods for goods, and both resell at a profit?”

“That depends,” Onetor said. “What have you got?”

“Papyrus and ink from Egypt…” Sostratos began. Onetor tossed his head. Sostratos said, “I did expect those would do better in Athens. I’ve also got Koan silk, which is worth its weight in silver, too.”

“It’s pretty stuff, but I’m not interested in it,” the truffle-seller said. “Kos isn’t that far from here; silk’s fairly common on Lesbos.”

“All right, best one,” Sostratos said. “I have fine beeswax from Ioudaia-”

“Anyone can find beeswax,” Onetor broke in. “All you have to do is know how not to get stung.”

“The Aphrodite carries fine wine from Byblos, with a bouquet as sweet as Ariousian’s,” Sostratos said. “I’m not making that up. We carried Ariousian to Great Hellas a few years ago, and this wine has a nose to match it.”

“Let everything be as you say, most noble one, and it sill wouldn’t matter much to me,” Onetor replied. “Onesimos is the wine merchant in the family. He might be interested in this vintage from far away, but I’m not, except maybe to taste a cup. What else have you got on that akatos?”

“Embroidered linen cloth from Mesopotamia,” Sostratos said. “Fine perfume from Rhodes, the island of roses. And genuine balsam from Engedi on the Lake of Asphalt in Ioudaia, the finest balsam in the world.”

“Balsam, eh?” Onetor scowled. “What do you want for that? It’s something I might be able to get rid of here on Lesbos.”

“They sell it in Ioudaia for twice its weight in silver,” Sostratos answered.

“Somesimes they sell it here in Hellas for twice its weight in silver, too,” Onetor said pointedly.

“Not always,” Sostratos said, just as pointedly. “And if I paid twice its weight, and I did, I’m not going to let it go for no profit. If you buy it from me, you won’t sell it at your buying price, either.”

“All that may be true-if you paid what you say you paid. But who knows about that?” Onetor sent Sostratos a sour stare. “Merchants are born liars.”

“No doubt you would know, being one yourself,” Sostratos said. Onetor’s expression got blacker. Sostratos gave him a polite seated bow. “We can go on insulting each other, best one, or we can do business. Which would you rather?”

Now the Mytilenean frankly stared. “You’re a cool customer, aren’t you?

“I try to stay cool, and I would like to be a customer,” Sostratos replied. “Shall we talk about balsam and truffles, or shall we go on and on about what a thief each of us thinks the other one is?”

To his surprise, Onetor started to laugh. “You are a cool customer, Furies take me if you’re not. All right, my dear, let’s talk about trading truffles for balsam, and just how much balsam you’ll give for a drakhma’s weight of my fungi. Maybe perfume, too, now that I think of it.”

Sostratos hadn’t expected anyone to be interested in balsam till he got to Athens. But he had a good notion of the most he could hope to get for it there. That, clearly, was less than he could get for truffles. Because Onetor had annoyed him, he named an outrageous price to open the dicker. As he’d hoped, the truffle-seller bawled like a castrated colt. Sostratos came down, but, because he’d started so high, he came down to a price he still liked.

Onetor had made a mistake, setting the value of his truffles so firmly as the dicker started. He’d made it plain he wouldn’t come down, but he couldn’t very well go up from the three drakhmai of silver for each drakhma’s weight of truffles, either. Sostratos was more flexible, and took advantage of that when haggling over both the balsam and the perfume. At last, he and the Mytilenean settled on prices that left neither of them too dissatisfied.

“While we’re talking here, my cousin is dickering with your brother,” Sostratos remarked.

“I hope Onesimos comes out of the deal with all his fingers and toes,” Onetor said. “If Menedemos is anywhere near as sharp as you are, best one, he’s too good for us poor fellows who stay in one polis all our days.”

“You give me too much credit, most noble one,” Sostratos murmured, not at all displeased at Onetor’s flattery. “And,” he went on truthfully, “you don’t give yourself enough. I think this is a bargain where we’ll both end up showing a nice profit.”

“I wouldn’t mind,” Onetor said. “For a while there, I thought you were going to talk me out of my skin and sell it in the Athenian agora.”

“Who’s your prettiest hetaira here? I’d get a better price for hers,” Sostratos said. Onetor laughed. The Rhodian asked, “Can you have your truffles ready this afternoon? I’ll have sailors bring the balsam and perfume here then, if that pleases you.”

“It pleases me fine. And if you’re going to get an amphora or two of Phainias’ oil and flavor it with truffles, you might also want to arrange to buy lekythoi here in Mytilene so you can sell the oil from the small jars. Kallikrates son of Kalligenes can probably sell you enough of them to do the job without making you wait.”

Sostratos wondered if this Kallikrates would give Onetor a kickback, but getting away in a hurry did matter. “I’ll talk with him,” he said. “Where’s his pottery?”

“Not far from here. Phainias can give you directions; he buys all his amphorai from Kallikrates,” Onetor said. That made Sostratos feel better. If the Rhodian proxenos bought from Kallikrates, the man was likelier to be reputable.

When he and Menedemos met at Phainias’ house, he found his cousin jubilant. “We’ll take Lesbian to Athens along with the Byblian,” Menedemos said. “Do you know what I did? Do you know?” He was almost beside himself with glee.

“No,” Sostratos replied, “but I suspect you’re going to tell me.”

“I traded him ten jars of Byblian for thirty of his best,” Menedemos said. “Ten for thirty! Can you believe it?”

“Euge!” Sostratos and Phainias both spoke together. The proxenos went on, “How did you pry such a bargain out of Onesimos? He’s one of the singiest men I know.”

“You won’t tell him?” Menedemos asked.

“By Zeus, best one, I won’t,” Phainias promised. “It would go against my duty as proxenos-and besides, Onesimos should deal in vinegar, he’s so sour.”

“Well, I thought so, too,” Menedemos said. “We were talking about wine, and I made sure we tried his Lesbian before he sent a slave down to the harbor to bring back my sailors with a jar of Byblian for him to sample. We’d had quite a bit of his wine before then, in fact. He thought he was getting me drunk and pliable. I had something else in mind, though.”

“I think I know what,” Sostratos said. “You are a sly rascal.”

“Why, thank you, my dear.” Beaming, Menedemos turned back to Phainias. “When the slave and the sailors got back with the Byblian, we broached the amphora. What you need to know about Byblian is, it has the most wonderful bouquet in the world. Maybe Ariousian is as nice on the nose coming out of the jar, but I can’t think of any other wine that is.” He sniffed and smiled and went on, “When Onetor got a whiff of it, he was so excited, he almost looked happy.”
