"Clockpunk is a genre of speculative fiction that explores the concept of technology based on clockwork and Renaissance-era science rather than on steam power, the internal combustion engine or digital computers. It can take the form of alternate history, fantasy or simply an aesthetic.
A clockpunker’s home period is the Renaissance. Thus, he or she must be a Renaissance man or woman, able to spend the day building a flying clockwork battleship, the evening dancing the pavane, and still have the dexterity of hand to slip arsenic into a neighbor’s wine. Creativity, genius, charisma and ambition are all essential qualities for success. Nothing is impossible to the talented and the determined, but beware: the road to greatness is treacherous."
