The Codex Sinaiticus, a fourth-century A.D. manuscript discovered in St. Catherine’s Monastery at the foot of Mt. Sinai, contains a truncated version of the once widely read Greek text The Shepherd of Hermas. This codex also includes one of the earliest complete copies of the Greek Septuagint, translated from Hebrew in the third century B.C. Here, the Codex Sinaiticus is open to the beginning of the text, which recounts Hermas’s first vision.
