An inscription on a 3,500-year-old stone block from Egypt may be one of the world’s oldest weather reports—and could provide new evidence about the chronology of events in the ancient Middle East.

Santorini tree rings support the traditional dating of the volcanic eruption

Will the dating of the volcanic eruption of Santorini remain an unsolved mystery? The question whether this natural disaster occurred 3,500 or 3,600 years ago is of great historiographical importance and has indeed at times been the subject of heated discussion among experts.
