The Mishnah, meaning “teaching” is the written compilation of the oral Torah, also believed to have been revealed at Sinai. It includes laws and observances having to do with agriculture, holy seasons, women, family, civil law, temple rituals, and laws of purity. The Mishnah was compiled in the 2nd century CE by Rabbi Judah HaNasi (literally “Judah the Prince”) and became the basis of the monumental code of law, the Talmud.
