We have been privileged to experience the work of many masters during our continuing journey around the globe. The skills of these masters, some long dead while others still in their prime, are shattering. The designers of Machu Picchu, the Colosseum and the Burj Khalifa must have been built with equal parts know how, confidence and ambition. Michelangelo's Rome is filled with many examples of his mastery. His sculptures, paintings and buildings bowled us over. So much beauty and so much talent.
