Most bibliophiles would agree to this maxim: the older the book, the better. If so, a forthcoming lot at Christie’s offers the chance of a lifetime as the auctioneer is selling the oldest tome you are ever likely to see.

The oldest known book in private hands is one of two lots at the auction that can be said to be among the most important texts in the history of early Christianity.

Eugenio Donadoni, a senior specialist in books and manuscripts at Christie’s, said the texts were of “huge international significance”, adding: “They are really important touchstones in charting early Christianity.”
