The formation of an urban society and the innovations that came with it and which occurred for the first time in Uruk – a regional and supraregional centre – had an enormous impact on the entire Near-Eastern world. Very quickly, impressive temples and palaces sprung up, overshadowing the early grand architectural monuments in Uruk’s centre. A striking feature of these new buildings was their form, the ziggurat or stepped tower, which went on to become a defining element of ancient Near-Eastern temple architecture. The use of writing as an administrative tool also laid the foundations for science and learning in the ancient Near East. Very early on, lexical lists of terms and objects began to emerge – the first of their kind – and these were passed down the generations. Some of these records contain lists of city officials and specialist terms for occupations that provide an insight into a highly stratified society. Other records bear lexical lists of everyday objects, providing an insight into material culture. Particular importance was given very early on to observing the stars as a means to read the future. The ancient Babylonian palace of the ruler Sin-Kashid, built in the 2nd millennium BCE, exemplifies Uruk’s role as part of the ancient Near-Eastern empire. The palace served as both the seat of the ruler and as a commercial and administrative centre. It was here that diplomatic correspondence, legal contracts, surety bonds, and various court documents were set in writing. The site also served as a lively trading centre. Deliveries of raw materials were processed into valuable goods that denoted the owner’s status. The palace was also a place where writers were educated. The writers played a vital role in everyday life, as they compiled the correspondence and contractual agreements on behalf of the largely illiterate population.
