More than a decade before the hobnailed boots of Pompey the Great scraped the pavers of the Jerusalem Temple,* the Roman commander was out West. On the Iberian Peninsula, he pursued a campaign against the guerrillas of Quintus Sertorius. This pursuit kept Pompey busy for five years, from 76 to 71 BC. In that half-decade, Pompey developed his military chops, demonstrated a reputation for brutality, and earned a Roman triumph. The experience would serve him well.
