The year was 1170 when the Rambam began his magnum opus. Ten years later he completed the Mishnah Torah. The work is a monumental compilation, and orderly arrangement of all biblical and rabbinic rules, practices, and customs. The Mishneh Torah is an unparalleled masterpiece of comprehensive halachic knowledge covering almost every topic of jewish life including medicine as the Rambam was the personal doctor to the sultan.
This edition of Mishneh Torah is considered to be the best and clearest edition yet.
