Christian apologist William Lane Craig says that forty years is too short a period for legend to develop. He points to a claim made by A.N. Sherwin-White in Roman Society and Roman Law in the New Testament (1963).
According to Sherwin-White, the writings of Herodotus enable us to determine the rate at which legend accumulates, and the tests show that even two generations is too short a time span to allow legendary tendencies to wipe out the hard core of historical facts. When Professor Sherwin-White turns to the gospels, he states that for the gospels to be legends, the rate of legendary accumulation would have to be “unbelievable.” More generations would be needed.

Craig’s summary has been quoted widely and was popularized in Lee Strobel’s The Case for Christ (2008), and it sounds like a thorough slap down of the legend claim. However, when we see what Sherwin-White actually said, we find that Craig’s confidence is unwarranted.
(From this point forward, I’ll use “SW” to refer to historian A.N. Sherwin-White.)
SW never said “unbelievable”
Incredibly, the word “unbelievable,” which Craig puts into the mouth of SW, is not used by him in the relevant chapter in this book. If the word comes from another source, Craig doesn’t cite it. Craig also quotes the word in his essay in Jesus Under Fire (1995).
We all make mistakes, but it’s been twenty years. Where is Craig’s correction?
What did SW actually say?
From his Roman Society and Roman Law in the New Testament:
Herodotus enables us to test the tempo of myth-making, and the tests suggest that even two generations are too short a span to allow the mythical tendency to prevail over the hard historic core of the oral tradition. (RSRL, 190)
SW proposes an interesting experiment. If we can find examples in history where legend has crept into oral history and we have more reliable sources that let us compare that with what actually happened, we can measure how fast legendary material accumulates.
Notice the limitations in what SW is saying.
- He cites several examples where historians have (tentatively) sifted truth from myth, but Herodotus is the only example used to put a rate on the loss of historic truth. This isn’t a survey of, say, a dozen random historic accounts that each validates a two-generation limit.
- He isn’t saying that myth doesn’t accumulate, and he’s not proposing a rate at which it does. He’s writing instead about the loss of accurate history (“the mythical tendency to prevail over the hard historic core”).
- He is careful to use the word “suggest” above. William Lane Craig isn’t as careful and imagines an immutable law that SW clearly isn’t proposing.
What is SW’s point?
Here is more of what SW is saying.
All this suggests that, however strong the myth-forming tendency, the falsification does not automatically and absolutely prevail. (RSRL, 191)
The point of my argument is not to suggest the literal accuracy of ancient sources, secular or ecclesiastical, but to offset the extreme skepticism with which the New Testament narratives are treated in some quarters. (RSRL, 193)
Craig imagines that myth never overtakes historic truth in two generations. By contrast, SW says that myth doesn’t always overtake historic truth.
Consider Craig’s difficulty. He proposes what may be the most incredible story possible: that a supernatural being created the universe and came to earth as a human and that this was recorded in history. We have a well-populated bin labeled “Mythology” for stories like this. If Craig is to argue that, no, this one is actually history, SW’s statement is useless. “Well, myth might not have overtaken historic truth in this case” does very little to keep Craig’s religion from the Mythology bin.
