Alexander the Great!

In the British Museum, a marble portrait of Alexander the Great is on display.  It looks like this:

The following is an excerpt from the British Museum's website, www.britishmuseum.org:

Marble portrait of Alexander the Great

Hellenistic Greek, 2nd-1st century BC
Said to be from Alexandria, Egypt

Youthful image of the conqueror king

Literary sources tell us, though perhaps not reliably, that Alexander (reigned 336-323 BC) chose only a few artists to produce his image, and famous names such as the sculptor Lysippos and the painter Apelles were associated with his portraiture. Though none of the famous images have been recovered, many sculptures in different materials, as well as portraits on gemstones and coins, survive. These were mostly produced long after Alexander's death and while the portraits follow similar general characteristics, they also vary in style.

Alexander was always shown clean-shaven, which was an innovation: all previous portraits of Greek statesmen or rulers had beards. This royal fashion lasted for almost five hundred years and almost all of the Hellenistic kings and Roman emperors until Hadrian were portrayed beardless. Alexander was the first king to wear the all-important royal diadem, a band of cloth tied around the hair that was to become the symbol of Hellenistic kingship.

Earlier portraits of Alexander, in heroic style, look more mature than the portraits made after his death, such as this example. These show a more youthful, though perhaps more god-like character. He has longer hair, a more dynamic tilt of the head and an upward gaze, resembling his description in literary sources.

This head was acquired in Alexandria, the city founded by Alexander in 331 BC, and the location of his tomb. Alexandria was also the capital of the longest surviving Hellenistic dynasty, the Ptolemies. From the time of the reign of Ptolemy I Soter ('Saviour') (305-282 BC), Alexander was worshipped as a god and the forefather of the dynasty.

The 3D printer was used to try to bring this to life for the students, and this was the result:

The original sculpture that this portrait was taken from may have been created by Lysippos.  

Lysippos "...was a Greek sculptor of the 4th century BCE. Together with Scopas and Praxiteles, he is considered one of the three greatest sculptors of the Classical Greek era, bringing transition into the Hellenistic period. Problems confront the study of Lysippos because of the difficulty of identifying his style amongst the copies which survive. Not only did he have a large workshop and a large number of disciples in his immediate circle,^[2] but also there is understood to have been a market for replicas of his work which was supplied also from outside his circle already in his own lifetime and also later in the Hellenistic and Roman periods" (source: wikipedia).

Here are a couple pieces thought to have been created by Lyssipos:

 Hermes of Atalante

Socrates
