Slavery in Babylonia was a part of the society, and it will be mentioned in this book again and again. It is a controversial subject, but I hope the readers will realize that it was entirely different from what we know of slavery in the modern world. Most of the slaves were Babylonians of the same race and nationality as their masters, spoke the same language, and worshipped the same gods. The slave was regarded as a member of the family and was educated at the same level, so many slaves were skilled artisans and even had literary or scientific knowledge. Many times slaves were adopted by their owners and thus became free citizens. The lines separating slavery and freedom were fuzzy anyway, since a man or a woman could sell themselves to settle a debt, and later acquire their freedom by various means. Parents could sell their children, and in certain circumstances brothers could sell their sisters if they were minors and the parents were dead.
