Jewish time: First stages of seasonal hours in Judea.

Research output: Contribution to journalArticlepeer-review


• The Aramaic Astronomical Book of Enoch is using seasonal rather than fixed time units. • This use in seasonal time units can be regarded as the first introduction of seasonal hours into Jewish culture. • The astronomy of the AAB is more accurate and sophisticated than previously assumed. • This new understanding of the AAB connects it to Neo-Babylonian astronomical texts.
