Vitruvius Quotes
In felling a tree we should cut into the trunk of it to the very heart, and then leave it standing so that the sap may drain out drop by drop throughout the whole of it... Then and not till then, the tree being drained dry and the sap no longer dripping, let it be felled and it will be in the highest state of usefulness.

Marcus Vitruvius Pollio (/vɪˈtruːviəs ˈpɒlioʊ/; c. 80–70 BC – after c. 15 BC), commonly known as Vitruvius, was a Roman author, architect, and civil and military engineer during the 1st century BC, known for his multi-volume work entitled De architectura. He originated the idea that all buildings should have three attributes: firmitas, utilitas, and venustas ("strength", "utility", and "beauty"). These principles were later widely adopted in Roman architecture. His discussion of perfect proportion in architecture and the human body led to the famous Renaissance drawing of the Vitruvian Man by Leonardo da Vinci.
