Explanation:
Akkadian Period
Sargon of Akkad’s (reigned c. 2334–c. 2279 BCE) unification of the Sumerian city-states and creation of a first Mesopotamian empire profoundly affected the art of his people, as well as their language and political thought. The increasingly large proportion of Semitic elements in the population were in the ascendancy, and their personal loyalty to Sargon and his successors replaced the regional patriotism of the old cities. The new conception of kingship thus engendered is reflected in artworks of secular grandeur, unprecedented in the god-fearing world of the Sumerians.
Architecture
One would indeed expect a similar change to be apparent in the character of contemporary architecture, and the fact that this is not so may be due to the paucity of excavated examples. It is known that the Sargonid dynasty had a hand in the reconstruction and extension of many Sumerian temples (for example, at Nippur) and that they built palaces with practical amenities (Tall al-Asmar) and powerful fortresses on their lines of imperial communication (Tell Brak, or Tall Birāk al-Taḥtānī, Syria). The ruins of their buildings, however, are insufficient to suggest either changes in architectural style or structural innovations.
Sculpture
Two notable heads of Akkadian statues have survived: one in bronze and the other of stone. The bronze head of a king, wearing the wig-helmet of the old Sumerian rulers, is probably Sargon himself. Though lacking its inlaid eyes and slightly damaged elsewhere, this head is rightly considered one of the great masterpieces of ancient art. The Akkadian head in stone, from Bismāyah, Iraq (ancient Adab), suggests that portraiture in materials other than bronze had also progressed.

Where relief sculpture is concerned, an even greater accomplishment is evident in the famous Naram-Sin (Sargon’s grandson) stela, on which a pattern of figures is ingeniously designed to express the abstract idea of conquest. Other stelae and the rock reliefs (which by their geographic situation bear witness to the extent of Akkadian conquest) show the carving of the period to be in the hands of less competent artists. Yet two striking fragments in the Iraqi Museum, which were found in the region of Al-Nāṣiriyyah, Iraq, once more provide evidence of the improvement in design and craftsmanship that had taken place since the days of the Sumerian dynasties. One of the fragments shows a procession of naked war prisoners, in which the anatomic details are well observed but skillfully subordinated to the rhythmical pattern required by the subject.
Some compensation for the paucity of surviving Akkadian sculptures is to be found in the varied and plentiful repertoire of contemporary cylinder seals. The Akkadian seal cutter’s craft reached a standard of perfection virtually unrivaled in later times. Where the aim of his Sumerian predecessor had been to produce an uninterrupted, closely woven design, the Akkadian seal cutter’s own preference was for clarity in the arrangement of a number of carefully spaced figures.
