Kanon (visual novel)
Most of "Kanon"s development staff originally worked for the visual novel publisher Nexton under the brand Tactics. After the release of the brand's third game "", most of Tactics' staff left Nexton to pursue work in another publishing company where they could have the freedom to produce their next game. Itaru Hinoue, who had previously worked at VisualArt's once before, introduced Key's founding members to the president of VisualArt's, Takahiro Baba. Baba gave the developers the freedom they desired, and they officially transferred to VisualArt's where they formed Key on July 21, 1998 and started production on "Kanon". The planning for the visual novel was headed by Naoki Hisaya who was also one of two scenario writers with Jun Maeda. Hisaya wrote the scenarios for Ayu, Nayuki and Shiori, while Maeda wrote the routes for Makoto and Mai. Art direction was headed by Key's artist Itaru Hinoue who worked on the character design and computer graphics. Further computer graphics were split between three people—Dinn, Miracle Mikipon, Shinory—and background art was provided by Torino. The music in the game was composed by OdiakeS, Shinji Orito and Jun Maeda. "Kanon" was the first and last visual novel developed by Key that two of the main staff—Naoki Hisaya, and OdiakeS—worked on before pursuing a similar line of work in other visual novel studios.
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.
