Herodotus, the Greek historian reports Macrobians as having mastered longevity, with the average Macrobian living until the age of 120. They were said to be the "tallest and handsomest of all men"
The Macrobians were part of an expanse of related peoples, kinsmen of the Ancient Egyptians, that inhabited an area stretching from East Africa northward into Egypt and North Africa. At the same time, they were reported as being physically distinct from the general inhabitants of the region below the Sahara
Macrobia was also noted for its gold, which was so plentiful that the Macrobians shackled their prisoners in golden chains.
