What people thought of primes through the history
Prime number (as the one defined by Aristotle, Euclid and Theon of Smyrna) is a number "measured by no number but by an unit alone" Iambilicus said that a prime number is also called "odd times odd".
Prime number was apparently first described by Pythagoras.
Iamblichus writes that Thymaridas called a prime number rectilinear since it can only be represented one-dimensionally.
In English prime number is found in Sir Henry Billingsley's 1570 translation of Euclid's Elements (OED2).
Some older textbooks include 1 as a prime number.
