Fans of Asterix often wonder how much of the series is rooted in real history. While René Goscinny and Albert Uderzo primarily drew inspiration from modern stereotypes and Julius Caesar’s Commentarii de Bello Gallico, the ancient historian Diodorus Siculus (1st century BCE) provides valuable context for the Gaulish world that the comics lovingly parody. His Bibliotheca historica preserves descriptions of the Gauls, Rome, and other ancient peoples, giving a glimpse of the historical realities behind the humour.

The Look of the Gauls

Diodorus, drawing on earlier accounts by Posidonius, described the physical appearance and habits of the Gauls in ways that resonate with Uderzo’s illustrations:

• The Moustache: Gallic men shaved their cheeks but let their mustaches grow long—sometimes covering the mouth. This detail appears exaggerated yet recognisable in the comics.
• The Hair: Diodorus mentions the use of lime (or similar substances) to stiffen and lighten hair, reflecting the bright, spiky hairstyles seen in the village.
• Boisterous Feasting: The Gauls were fond of loud banquets, echoing the lively closing feasts in every album.

Roman Expansion and Julius Caesar

Diodorus chronicles the Roman Republic’s military campaigns and expansion across Gaul and the Mediterranean. While Caesar’s Commentarii is the primary source for the comics’ narrative and style, Diodorus confirms the scale and organisation of the Roman legions, highlighting why the tiny Gaulish village’s resistance is so remarkable.

Egypt and Cleopatra

In Asterix and Cleopatra, the comics parody the grandeur of ancient Egypt. Diodorus’ detailed descriptions of Egyptian society, monuments, and religion provide historical grounding:

• Monuments: His accounts of the Pyramids and the Sphinx show why Greeks and Romans regarded Egypt as awe-inspiring—a sentiment the comics exaggerate humorously.
• Clarification: The joke about Cleopatra’s nose originates from Blaise Pascal in the 17th century, and the album’s storyline draws inspiration from the 1963 Hollywood film Cleopatra.

Western Mediterranean Peoples

Diodorus describes Iberians, Lusitanians, and other western Mediterranean groups. While the albums set in Spain and Lusitania exaggerate modern stereotypes like flamenco or slow work ethic, the geography and tribal contexts are historically based.

Britain and the Britons

Diodorus mentions the Britons’ tin trade and relatively “simple” habits. The comics playfully twist this simplicity into humorous portrayals of tea-drinking, warm beer, and other anachronistic British traits.

The Pirates

One of the series’ most beloved running gags—the hapless pirates constantly sunk by Asterix and Obelix—is a parody. Diodorus accurately records that piracy was a significant problem in the ancient Mediterranean, providing the historical setting, but the characters themselves visually reference the French comic Barbe-Rouge (Redbeard).

Conclusion

Diodorus Siculus’ ethnographic and historical accounts built the stage for stories Goscinny came up with. The result is a world that is both historically recognisable and hilariously unique.
