The first calculation of the golden ratio was described by Euclid in his Elements (Greek: Στοιχεῖα)
Euclid's Elements (Greek: Στοιχεῖα) gives the first known written definition of the golden ratio: "A straight line is said to have been cut in extreme and mean ratio when, as the whole line is to the greater segment, so is the greater to the less."Cite error: The <ref>
