The lives and actions of the nad tum women in Old Babylonian society have become known to us mainly through cuneiform texts from the city of Sippar, recording the economic transactions of this group of women. They were religious devotees, living under strict regulations, such as celibacy, but they also vividly engaged in the city's economic life. The Old Babylonian nad tum has been the subject of many studies, that have enlightened the nad tum as an actor in the economic system, as well as provided insight in many other aspects of the Old babylonian society. This book attempts to form a compilation of the knowledge of the nad tum as businesswoman.
