Echoes From Ancient Egypt Unveiled at the memorial Art Gallery last spring, the 2,400-year-old coffins of Egyptian official Pa-debehu-Aset are slated to become a focal point of the museum's Egyptian collection. A pair of 2,400-year-old Egyptian coffins is providing visitors to the Memorial Art Gallery a rare glimpse of life on the Nile more than two millennia ago. The coffins-an inner and outer set-of Pa-debehu-Aset, an Egyptian official who lived during the Ptolemaic era of Egypt in the 4th century B.C.E., went on display last spring. Only two other comparable sets from the same period are known to exist.
