Isaiah
Miniature of Isaiah, manuscript illumination from The Siegburg Lectionary, 12th century.
The writings known as Deutero-Isaiah—which comprise chapters 40–55 of the Book of Isaiah—were composed during the Babylonian Exile in the 6th century BCE.1
While the first 39 chapters of the book are attributed to the 8th-century prophet Isaiah, chapters 40–66 are recognized as being of much later origin. Scholars further distinguish between Deutero-Isaiah (chapters 40–55) and Trito-Isaiah (chapters 56–66), the latter of which reflects a still later period and a Palestinian perspective.12
