It is not well-known that classical authors attributed gigantic heights to ancient Greek heroes.
In his work Heroikos ("On Heroes", ca. AD 230), the sophist Philostratus the Lemnian addresses the general belief that ancient heroes averaged more than 10 cubits -equivalent to more than 4 meters or 12 feet- in height. Philostratus mentions, as an empirical evidence for giant heroes, the findings of enormous bones in the places where the heroes' tombs were traditionally assumed to lie.
On the basis of the sizes of those bones, Philostratus states that, for instance, Orestes -one of Agamemnon 's children- reached 3 meters or 10 feet; Ajax -king of Salamis and a principal character in Homer's Iliad- was not less that 4.5 meters or 15 feet tall; and Achilles -the greatest warrior of the Trojan war, according to Homer- was a colossus 10 meter or 33 feet in height.
The following figure shows a comparison of the height of these three heroes with each other and with a normal modern man (1.8 m or 6 ft).
From a normal man's perspective, the three giants should have looked as shown below.
It is now believed that Philostratus's accounts should have been inspired by the discovery of fossil bones of big Tertiary mammals -such as mammooths or extinct rhinoceroses- which are still frequent in several locations of the Greek Mediterranean. This historical explanation doesn't prevent us to imagine some scenes featuring Philostratus's giant heroes and normal men, as in the following pictures.
