Researchers using text-analysis software say they've discovered a new literary device in the first book of the Bible: the "Genesis death sandwich."

The name refers to a familiar rhetorical structure — sandwiching bad news in between the good. In the case of Genesis, the slices of white bread are themes of life, and the slimy cold cuts in between are mentions of death.

"The structuring of life and death in Genesis appears to be something that hasn't been noticed before," researcher Gordon Rugg, a senior lecturer in Computing and Mathematics at Keele University in the United Kingdom, wrote in a Feb. 21 blog post. "We think it's a standard literary device being used on a larger scale than had been previously realized. No aliens, no secret codes, no conspiracies, but some striking images, and a great name for a band."

For their study, Rugg and his colleagues ran the King James version of the text through software known as the Search Visualizer, which plotted mentions of life in red and death in green on a single gridded page representing the whole book. Their results showed frequent mentions of life in the opening and closing verses of Genesis, while themes of death were clustered in the middle. They say the device is an example of a literary convention known as inclusio, also called bracketing, where one theme frames another.

Rugg acknowledged that it is uncertain whether or not this "death sandwich" convention was applied to the text intentionally. Nonetheless, he says it might have been used to cushion the negative messages of death, or perhaps to put life and death in stark contrast. [The 10 Weirdest Ways We Deal With the Dead]

"Whether it was a deliberate use of inclusio or a subconscious use is an open question," Rugg wrote. "We don't think that this structure is likely to be a coincidence, given the number of times the two words occur within Genesis, and given that these are themes that have long been recognized as significant within it."

Rugg and his colleagues ran other searches using the software for words not considered significant by scholars, finding no specific patterns in the book of Genesis. However, they did find the word "woman" appears overwhelmingly in the first part of Genesis, while it rarely pops up in the second half, Rugg wrote. Another term, "begat," illustrates something scholars have long recognized -- that the gospels of Matthew, Mark, Luke and John mirror the themes and structures of the Old Testament (which includes Genesis); sure enough, "begat" showed a striking cluster in the first part of Genesis, mirroring what was found in the first part of the gospel of Matthew, Rugg said.

Rugg and David Musgrave of Amridge University in Alabama presented their research at November's meeting of the Association of Schools of Oriental Research in Chicago.
