“Is that part of your augur’s outfit?” she said.

“No. It’s a family heirloom. My grandfather gave it to me when I ten years old. I wear it only on special occasions.”

“May I touch it?”

“Of course.”

She reached up to touch the little lump of gold, which was vaguely cruciform in shape.

“I remember the day my grandfather gave it to me. He showed me the proper way to wear a toga, and then took me all around the city, just the two of us. He showed me the exact spot where his great-uncle, Julius Caesar, was murdered. He showed me the Great Altar of Hercules, the most ancient shrine in the city, which was erected by the Pinarius family in the days before Roma even existed. He showed me the fig tree on the Palatine where Romulus and Remus and their friend Pinarius climbed among the branches. And finally he showed me the Temple of Venus that Caesar built, and that was the first time I saw the fantastic golden statue of Cleopatra inside. My grandfather knew Cleopatra very well, and he knew Marcus Antonius, too. Someday… someday I want to have a son, and take him to see all those things, and tell him about his ancestors.”

Acilia still held the amulet. As he spoke, she had drawn closer to him, until her body pressed gently against his. She gazed at the amulet, then looked up into his eyes.

“But what sort of amulet is this? I can’t make out the shape.”

Lucius shook his head. “It’s funny, my grandfather made such a fuss about giving it to me, but even he wasn’t sure what it’s supposed to represent or where it came from. He only knew that it had been in the family for many generations. The original shape must have worn away over so many lifetimes.”

“There’s nothing like that in our family,” said Acilia, clearly impressed. She was so close that Lucius felt an urge to put his arms around her and hold her tightly against him, no matter that her brother might appear at any moment. But the sky above them suddenly opened and pelted the garden with rain. The raindrops were warm, and Lucius would have been happy to stand there, holding her, both of them getting soaking wet, but Acilia dropped the amulet, seized his hand, and with a shriek of laughter pulled him through the peristyle and into the house.
