NE of the Principal Things the Architect ought to consider, is the Convenience of the place where he would Build the Fabrick. This is the reason that Dinocrates was blamed by Alexander, for having propos'd him an Excellent Design for Building a City in a Barren place, and incapable of Nourishing those who were to Inhabit it.
We must then choose a place that is fertile, and hath abundance of every thing; and which hath likewise Rivers and Ports capable of furnishing it with all the Product and Commodities of the adjacent Countries.
The Third thing to be considered is, whether the Air be wholesome; and for this End, we must choose a high situated place, that it may be less Subject to Fogs and Mists; it must be likewise far from all Morasses, because the Corruption that may be caused by the infectious Breath of Venomous Beasts which commonly are ingendred there, makes the place very unwholsom, unless these Morasses be near the Sea, and situated high, that the Water may fall easily from them into the Sea, and that the Sea may likewise sometimes overflow them, and by its Saltness kill all the Venomous Beasts.
It is likewise to be remark'd, That a City situated upon the Sea, must needs have an unwholsom Air, if it be towards the South or the West; for generally the Heat weakens Bodies, and the Cold strengthens them; and so we see by Experience, that those who go out of a Cold Country into an Hot, have great difficulty to keep themselves in Health; whereas on the contrary, the Inhabitants of Hot Countries who go into Colder, have generally good Health.
The Ancients were accustomed to judge of the Quality of the Air, Water and Fruits, which might render a place wholsome by the Constitution of the Bodies of those Beasts which were nourished there, and to this End they consulted their Entrails; for if the Liver was Corrupted, they conjectured that the same thing must happen to Men that should Inhabit in that place.
