A spring may be seen to rise in Sicily which at certain times of the
year throws out chesnut leaves in quantities; but in Sicily chesnuts
do not grow, hence it is evident that that spring must issue from
some abyss in Italy and then flow beneath the sea to break forth in
Sicily. [Footnote: The chesnut tree is very common in Sicily. In
writing _cicilia_ Leonardo meant perhaps Cilicia.]
