This past week I had the fortune to visit Florence, Italy after a short business trip to southern Italy. The city blew my mind. I just couldn't comprehend how artists were able to accomplish so much with their bare hands. There was not a brick left to randomness. I was quickly reminded of Vitruvius' point of view relative to architecture in which he explained that a building should be guided by three basic principles: firmness, commodity and delight. The city still stands as if it was built yesterday; it still accommodates the needs of millions of visitors and Florence's beauty still continues to amaze whoever visits it.
