Multiplication, in Italian, German & French

Euclid's 300 BCE definition of multiplication was correctly translated into Italian, German and French in the 16th Century.

However, Henry Billingsley decided to substitute his own (defective) definition for Euclid's, so our multiplication definition hasn't made sense since 1570.

So, for the record, here are the links to Euclid's original Greek definition of multiplication, correctly translated prior to Billingsley.
