Every time you step into a museum, something new and fascinating swims into your consciousness. The magic happened again yesterday as I was in the most interesting British Museum exhibition, Sunken Cities, Egypt's Lost Worlds. Presenting amazing artifacts recovered from on-going underwater archeological work in the re-located sunken ports of Thonis-Heracleion and Canopus at the mouth of the Nile, the exhibition tells of the new insights into life in Egypt during the last four hundred years or so BC.
