Roman architect, engineer and planner, lived in the first century AD. Vitruvius Pollio's book De Architectura is thought to have been one of many Roman books on architecture but it is the only one which survives. Vitruvius described the aims of architecture as being Commodity, Firmness and Delight. For garden design, one could translate these objectives as Comfort, Stability, Health and Beauty. M.H. Morgan published an English edition of Vitruvius in 1914, accompanied by illustrations, like the 'Plan of Vitruvius Greek House According to Beckar'. Excavations at Pompeii produced many examples of houses and gardens of the type described by Vitrivius.
