Veni, vidi, vici. I came, I saw, I conquered. That was Julius Caesar's snappy slogan, sent back to the Senate in Rome to announce his victory over Pharnaces II. It was so memorable that people still know it by heart today. It uses alliteration, assonance and rhyme, and it's compressed into just three words. It's majestically assertive, and it's unarguable since it presents objective fact – but presents it with poetic power and immense authority.
