In the Introduction, I referenced a coin minted under the emperor Titus (Fig. E.1). On one side appeared the figure of the emperor sitting amid a heap of weapons, a reference to his roles in the Jewish War, the capture of Jerusalem, and the construction of the building depicted on the coin’s opposite side, the Flavian Amphitheater. The coin adopts an unusual perspective, showing the Colosseum’s façade while also permitting a glimpse into the building. We spy the columns tracing the uppermost reaches of the interior and a few heads peeping out between them. Lower down two more rings of spectators are visible, the lower one pierced by an entrance and split into wedges by staircases. When we last examined the coin, we remarked about how only one individual appeared – the emperor – while everyone else was merely an undifferentiated head.
