Does anyone know where I can find a free collection of portrait thumbnails? I can find a collection of ancient Han Chinese face thumbnails. However I am looking for a collection of thumbnails of faces of ancient Romans, Celts, Germans, Carthaginians, Greeks, Persians, Arabs, Berber, Illyrians, Thracians and Scythians. So far I've only been able to find a handful of face thumbnails of Romans and Celts of varying sizes. It has to be a collection of thumbnails of these ancient ethnicities and preferably thumbnails of uniform width and height.
