Vitruvius Gets Around

Vitruvius, the roman architect born c. 80–70 BC and died after c. 15 BC, identified three essential attributes of a building which are relevant to any item that we deal with.

A structure must exhibit the three qualities of

• firmitas, strong or durable
• utilitas, useful
• venustas, beautiful

Or as I like to say ...

• Firm
• Functional
• Friendly
  

I did not know that the famous picture of the man in the circle created by Leonardo da Vinci was called the Vitruvian Man
