DISCOVERY FILE / 01

1945NAG HAMMADI, UPPER EGYPT

THE TEXTS RESURFACE

A library beneath
the familiar story.

A collection of ancient Coptic books surfaced near Nag Hammadi in Egypt in 1945. Among them was the complete Gospel of Thomas: 114 sayings attributed to Jesus.

The books opened a much wider window onto early Christian thought. Exactly how they were found—and why they had been deposited there—remains a subject of scholarly debate.
