Early Israel and the Surrounding Nations by A. H. Sayce

One of the first facts which strike the traveller in Palestine is the smallness of a country which has nevertheless occupied so large a space in the history of civilised mankind. It is scarcely larger than an English county, and a considerable portion of it is occupied by rocky mountains and barren defiles where cultivation is impossible. Its population could never have been great, and though cities and villages were crowded together on the plains and in the valleys, and perched at times on almost inaccessible crags, the difficulty of finding sustenance for their inhabitants prevented them from rivalling in size the European or American towns of to-day. Like the country in which they dwelt, the people of Palestine were necessarily but a small population when compared with the nations of our modern age.
