Jun Maeda
After forming Key, Maeda worked on the music and scenario for their first title "Kanon" released in 1999, which proved to be very popular in the adult game market in Japan. Beside Maeda, the majority of "Kanon" scenario was written by Naoki Hisaya, but he quit Key shortly after "Kanon" was produced. Following this, Maeda wrote most of the scenario for Key's next title "Air", along with again working as the lyricist and one of the composers for the music featured in the game. After a period of four years in 2004, Key released their third and longest game "Clannad" where Maeda did a vast amount of the writing for the game; in all, Maeda put in around 75% of the work that went into the creation of "Clannad". Also in 2004, Maeda began writing his first manga entitled "Hibiki's Magic", which was first conceived as a short story he wrote as a student. In 2005, Maeda worked on the scenario and music for Key's fifth game "", followed by Key's sixth title "Little Busters!" released in July 2007 which he also worked on in regards to the scenario and music.
Polykleitos
Polykleitos consciously created a new approach to sculpture, writing a treatise ("Kanon") and designing a male nude (also known as "Kanon") exemplifying his aesthetic theories of the mathematical bases of artistic perfection. These expressions motivated Kenneth Clark to place him among "the great puritans of art": Polykleitos' "Kanon" "got its name because it had a precise commensurability ("symmetria") of all the parts to one another" "His general aim was clarity, balance, and completeness; his sole medium of communication the naked body of an athlete, standing poised between movement and repose" Kenneth Clark observed. Though the "Kanon" was probably represented by his "Doryphoros", the original bronze statue has not survived. References to it in other ancient writings, however, imply that its main principle was expressed by the Greek words "symmetria", the Hippocratic principle of "isonomia" ("equilibrium"), and "rhythmos". "Perfection, he said, comes about little by little ("para mikron") through many numbers". By this Polykleitos meant that a statue should be composed of clearly definable parts, all related to one another through a system of ideal mathematical proportions and balance.
