You can spell the possessive form "Eratosthenes's" if you wish, but it makes for a rather clumsy sound. It is quite common, in British English anyway, to omit the 's' following the apostrophe after a name or other noun that ends in 's', for reasons of euphony.
The two accepted forms for possessive singular nouns ending in s are:
Add an apostrophe (') after the existing s at the end of the word: Eratosthenes'
Add an apostrophe s ('s) after the existing s at the end of the word: Eratosthenes's
Examples:
Eratosthenes' life was devoted to science.
Eratosthenes's life was devoted to science.
Note: The -s's is the most commonly used form, but if you are a student, use the form that is preferred by your teacher.
