ultimate, it might be said, the only authority for the military and political facts given in this narrative,
is Thucydides. These facts have been admirably expounded and arranged by Grote, to whom everyone interested
in Greek history must be under obligations which cannot be adequately expressed. I have to acknowledge specially
my indebtedness to the maps which accompany the sixth volume of his history. In writing this little book
I have also had before me Mr. Haverfield's plan of Syracuse (executed in relief), and have found it very helpful.
