Physicists study the classics for hidden truths

Jul 24, 2012

The truth behind some of the world's most famous historical myths, including Homer's epic, the Iliad, has been bolstered by two researchers who have analysed the relationships between the myths' characters and compared them to real-life social networks.

In a study published online today, 25 July, in the journal EPL (), Pádraig Mac Carron and Ralph Kenna from Coventry University performed detailed text analyses of the Iliad, the English poem, Beowulf, and the Irish epic, the Táin Bó Cuailnge.

They found that the interactions between the characters in all three myths were consistent with those seen in real-life social networks. Taking this further, the researchers compared the myths to four known works of fiction -- Les Misérables, Richard III, Fellowship of the Ring, and Harry Potter -- and found clear differences.

"We can't really comment so much on particular events. We're not saying that this or that actually happened, or even that the individual people portrayed in the stories are real; we are saying that the overall society and interactions between characters seem realistic," said Mac Carron.

To arrive at their conclusions, the researchers created a database for each of the three stories and mapped out the characters' interactions. There were 74 characters identified in Beowulf, 404 in the Táin and 716 in the Iliad.

Each character was assigned a number, or degree, based on how popular they were, or how many links they had to other characters. The researchers then measured how these degrees were distributed throughout the whole network.

The types of relationships that existed between the characters were also analysed using two specific criteria: friendliness and hostility.

Friendly links were made if characters were related, spoke to each other, spoke about one another or it is otherwise clear that they know each other amicably. Hostile links were made if two characters met in a conflict, or when a character clearly displayed animosity against somebody they know.

The three myths were shown to be similar to real-life networks as they had similar degree distributions, were assortative and vulnerable to targeted attack. Assortativity is the tendency of a character of a certain degree to interact with a character of similar popularity; being vulnerable to targeted attack means that if you remove one of the most popular characters, it leads to a breakdown of the whole network – neither of these appears to happen in fiction.

Of the three myths, the Táin is the least believed. But Mac Carron and Kenna found that its apparent artificiality can be traced back to only 6 of the 404 characters.

"In terms of degree distributions, all three myths were like real social networks; this wasn't the case for the fictional networks. Removing the eponymous protagonist from Beowulf also made that network assortative, like real networks.

"For the Táin we removed the 'weak links' associated with the top six most connected characters which had previously offset the degree distribution, this adjustment made the network assortative," continued Mac Carron.

The researchers hypothesise that if the society of the Táin is to be believed, the top six characters are likely to have been fused together from other characters as the story passed orally through the generations.

The researchers acknowledge that there are elements of each of the myths that are clearly fantasy, such as the character Beowulf slaying a dragon; however, they stress they are looking at the society rather than specific events. Historical archaeological evidence has been interpreted as indicating that some elements of the , such as specific locations, landmarks and , are likely to have existed.

Fascinating stuff; I'd love to see some religious mythology subjected to this analysis also. By the way, the link doesn't work, anyone interested try this instead:

the Harry Potter books are fiction what would they be like without Hermione? or without Ron? or perhaps without Harry himself? i doubt they would be the same set therefore i would call that a breakdown

@Bowler:
In the Arxiv paper, there is an interesting note (P4-5) that, "For comparison, the degree distribution for the fictional
Universal Properties of Mythological Networks
narratives only follows a power law in the tail in one in-
stance (Harry Potter) and only this appears to be scale
free. The other three [fictional works], as the Marvel Universe, are better described by exponential distributions."
Which seems to indicate that a breakdown probably would occur in this work with the removal of one of those core characters (but most likely with Harry, similarly to Beowulf, as the highest degree character) and this network is perhaps more "reality-based" than some other fictional societies.

Do we take it, then, that these old myths originated in fact, embellished during re-telling throughout the ages?

the entire 7 book story stems from the fact that Voldemort tried to kill Harry, if there was no Harry then the books would probably be about Voldemort continuing to take over the world (unless someone else stopped him, which i doubt)

Pattern search of course, none of these myths have any historical persons.

If you do enough fictions, some will include traits that are identical to real events. Even so, we see how the researchers needed to adjust their data sets to fit their preconceived conclusions of some matches.

I wonder how they got that through peer review?

You have researched and traced the origins of all 1194 characters?

Yes. Many myths have true features - people are seldomly capable of producing ideas separate from reality.
