History

The earliest surviving written work on the subject of architecture is De architectura by the Roman architect Vitruvius in the early 1st century AD.[9] According to Vitruvius, a good building should satisfy the three principles of firmitas, utilitas, venustas,[10][11] commonly known by the original translation – firmness, commodity and delight. An equivalent in modern English would be:
Durability – a building should stand up robustly and remain in good condition.
Utility – it should be suitable for the purposes for which it is used.
Beauty – it should be aesthetically pleasing.
