Between Euclid's time and the time of the decline of the Western Roman Empire there were many scholars who wrote studies, called commentaries, of Euclid's Elements. The Athenian philosopher and mathematician Proclus (410-485) writes: "Before making a beginning with the investigation of details, I warn those who may read me not to expect from me the things which have been dinned into our ears ad nauseam by those who have preceded me... For I am surfeited with these things and shall give little attention to them." (Heath, The Thirteen Books of Euclid's Elements, 19)
