Over 2,500 years ago, a victorious army marched through the open gates of the mighty city of Babylon. Soon after came a decree: that all the conquered peoples who had been brought to the city — the people who helped build its magnificent temples, gardens, and palaces — could return to their homelands, to worship their own gods as they saw fit.In the many years since it was written, the edict has been interpreted in many ways: as a sign from God; as the first declaration of human rights; as a savvy piece of political propaganda.How much do the intentions of the person who wrote it matter, over two millennia later?
