historical trivia: Caesar admiration

Many of Rome's most ambitious emperors idolized Alexander the Great. When Julius Caesar was a 33 year-old general in Spain, he wept when he saw a statue of Alexander, lamenting that he had accomplished nothing, while Alexander had conquered the whole world by his age. The schizophrenic emperor Caligula built a bridge of wooden boats across the Bay of Naples and rode back and forth across it on a horse, wearing armor he stole from Alexander's tomb. Emperor Caracalla set out to conquer the same eastern lands Alexander had conquered, and made a great show of visiting his grave in Alexandria, Egypt.
