If we want to safeguard our languages, stories and ideas against extinction, we had better study Egyptology ... The scientific community has recently begun to think hard about natural and technological existential risks to human beings: a wandering asteroid, an unfortunately timed gamma-ray burst, a warming planet. But we should also begin to think about the possibility of cultural apocalypse. The Egyptian case is instructive: an epoch of stunning continuity, followed by abrupt extinction. This is a decline and fall worth keeping in mind. ... for all its carven glyphs, Egypt cannot claim to have passed down its dreams, memories and hopes for the future. Some of its civilisation has been recovered, but some was lost irretrievably. This is sobering enough on its own terms. When you examine our beloved present day from an Egyptological distance, you see that we are vulnerable to a similar fate. ... Imagine the pharaohs’ frustration at all the bits of language lost, the prayers and tributes especially. This was a civilisation that had its eyes fixed on eternity. Its civil calendar was apparently keyed to the heliacal rising of Sothis, whose astronomical cycle has a period of some 1,400 years. By dint of longevity, the first Egyptologists were Egyptian, and ditto the first tomb robbers. Is it a bridge too far to say the first futurists were Egyptian too? ... Cretan hieroglyphs remain impenetrable, Olmec – the language of the first major civilization in Mexico – is largely a mystery, and only within the past half-century or so has meaning been teased from the Mayan script. For every civilisation retrieved, another remains substantially beyond our comprehension.
