I used GAN and a 330 BC sculpture to find out what Alexander the Great looked like | by Ishtiaq Rahman | Archie.AI

Background:

I used a GAN or (generation adversarial network), a 330 BC bust of Alexander the Great by Leochares, and the picture of Alexander’s face by artist Jude Maris to create a lifelike portrait of Alexander the Great.

A generative adversarial network (GAN) is a machine learning framework designed by Ian Goodfellow. The concept was originally published in the 2014 paper titled “Generative Adversarial Networks”. The core idea is to create a system where 2 neural networks compete with each other in a game that generates new data with the same statistics as the training set. For example, a GAN trained on photographs can generate new photographs that look at least superficially authentic to human observers.

There is an opensource version of the underlying model I used here— GAN BREEDER — available on GitHub

I decided to use the image of the Head of Alexander, found near the Erechtheion of the Athens Acropolis in 1886 as the base image. It is thought to be an original work of the sculptor Leochares, made around 330 BC. Starting with this image made sense to me since it is the earliest and the cleanest depiction of Alexander I could get my hands on.

As for style, I used the interpretation of Alexander’s face by artist Jude Maris. Jude Maris used the Marble head of Alexander at the Istanbul Archaeological Museum as the base image.

The colour and other details were digitally added by the artist according to the artist’s interpretation of information available on Alexander’s appearance. (e.g. Heterochromia, blonde hair, sunburnt Greek/Masodanian complexion etc)

But since the image is based on a bust originally made a long time after Alexander’s death, I thought it would be worth it to use a more “contemporary” bust of Alexander to get a more accurate reproduction of the shape of his face.

Caveat: I think this is probably what Alexander looked like on his best days because I do not imagine sculptors would be inclined to depict Alexander the great on one of his bad days — which I am sure the great conqueror wasn’t immune to.
