Notes:

Bottom left is an image of a defeated and captured Gaul claiming the Romans as his heritage from the 19th century painting "Vercingetorix throws down his arms at the feet of Julius Caesar" by Lionel Royer, with stereotypical northwestern European features such as pale skin and light hair/eyes. The other images are mostly from the frescoes of Pompeii, a city in ancient Italy located right next to Rome (150 miles south). The ones that aren't from Pompeii are either Samnite tomb paintings or Etruscan tomb paintings from Tarqinia, another city in ancient Italy located right next to Rome (60 miles north). All are contemporary depictions of ancient Italians. They all show mostly people with typical Mediterranean features (olive skin, brown eyes, dark curly hair, etc.) plus a handful of fair-skinned blondes (this phenotype was- and isn't- unknown in in the Mediterranean, but it is/was rare). The Ancient Romans, looking pretty much modern Italians south of the Rubicon, considered phenotypes common in northwest Europe to be rare and exotic (cf. their descriptions of the "white-skinned" Gauls). The image satirizes three things: the old Nordicist racist myths about the Romans being secretly "Nordic", the common depiction (especially in Anglophone media) of the Romans as looking and sounding Northern European, and the tendency of Western European countries such as Britain and Germany to lay claim to the legacy of Rome when the Romans themselves saw those places as backwater homes of savage barbarians.
