The Arts and Sciences are all the crafts, skills, and technologies practiced in the time period and cultures that the SCA covers.
These include everything we do in the SCA from the cloths we wear, the armor we fight in, the blades we fence with and even the chairs we sit in.
Many of the member participate in many different types of A&S from sewing to dancing.
If you are interested in any particular Art or Science, chance are there is someone in the SCA who can help you learn, or at least point you in the right direction
