New York Kouros

The New York Kouros is one of the artifacts that officials determined had been stolen from archaeological sites. It is also one of the earliest marble statues of a human figure carved in Attica. The rigid stance, with the left leg forward and arms at the side, was derived from Egyptian art. The pose provided a clear, simple formula that was used by Greek sculptors throughout the sixth century B.C. In this early figure, almost abstract, geometric forms predominate; and anatomical details are rendered in beautiful analogous patterns. The statue marked the grave of a young Athenian aristocrat.

The statue is similar to the (near-contemporary) statue of Mentuemhet and represents an example of daedalic statuary style. The statue is stylized and not representational. It is highly geometric, and the body is idealized and abstracted, especially in the muscles and the areas of the joints. The eyes and face are not realistic to how a person would look; this statue is not attempting to be observational in nature. The motif of a male figure with his arms straight to his sides, standing upright, and facing forward is unmistakable. The kouros is stiff, rigid, and linear; there is little movement depicted and the figure's specifics aren't touched on in the overall body outline of the subject. However, the left foot is displayed as forward of the right foot, potentially signaling to the viewer that the kouros is walking.
This kouros was carved in Attica during the archaic period of Ancient Greece. It was a time that Greece was splintered into many city-states. Greek artists were making more and more naturalistic representations of the human figure throughout the 6th century BC. During this time, Greece was coming out of an orientalizing period, where Ancient Greece was increasingly influenced by various eastern and southern civilizations. This explains why the statue takes on a more natural look than previous Greek art yet still retains those orientalizing features—particularly the Egyptian influence, with whom they had considerable contact. Kouroi were often used as grave markers or dedications for the gods.
Many kouroi, in the style of this one, were typically heavily Egyptian influenced, with the left leg forward and arms to the side. Historical evidence suggests that Greeks had some familiarity with Egyptian technical procedures by this point and that Greek visitors to Egypt—charmed by the colossal Egyptian statuary they saw—persuaded Greek sculptors to adopt and augment the style to remove, in the words of Hurwit, Plantzos, and Campbell in Kouros, “the stone screens connecting legs and arms”, “the vertical slab against which Egyptian statues were usually set”, and to strip the subject matter down to the nude. They also used the Egyptian grid system.
The Department of Greek and Roman Art at the Metropolitan Museum of Art stated in Greek Art in the Archaic Period that through the proportions of the statue, as well as its pose, this particular kouros shows its influence from Egypt. 
In fact, like many other kouroi, the pose and stance itself was directly borrowed from Egyptian art, likely explaining its similarity to statues such as the statue of Mentuemhet and the iconography behind the similar stance and posture. 
This kouros served as the grave marker for a young Athenian Aristocrat and was produced by a person of the Attic culture. This is shown because in Athenian culture funerary monuments were especially popular for marking the graves of people who died young (but not necessarily depicting them). In these respects, this kouros is very typical for the Greek kouroi of the time.
