Ah; thanks. Thus the reason why all the debates arising from "The DaVinci Code". Your explanation also reminded me of something I saw on television (Discovery Channel, I think), about the Alvarez Asteroid Theory: a geologist was saying that the earth can be read like a book (facts, in other words); and that Alvarez Jr. or Sr. looked at a thin layer of dirt between Cretaceous and Tertiary rocks and found a much higher concentration of iridium than would normally be expected. Further examinations revealed the same finding in that layer all around the world. Therefore it seemed to be a fact that a huge asteroid hit the earth with such an impact that its iridium spread throughout the atmosphere, falling back to earth in this one thin layer, in which there were suddenly no fossils. So--I guess they "read" the earth and came up with this "fact", which sounds like historicity to me if I understood you correctly.
