QUOTE : It is not enough to live here and now. Not enough for me, anyway. I need those imaginative leaps out of my own time frame and into other places - places where things were done differently. Reading has provided me with that, for the most part, but it is objects, things like these scraps of pottery, that have most keenly conjured up all those elsewheres - inaccessible but eerily available to the imagination. The past is irretrievable, but it lurks. It sends out tantalizing messages, coded signals in the form of a clay pipe stem, a smashed wine bottle. Two leaping fish from twelfth-century Cairo. I can't begin to understand what that time was like, or how the men who made them lived, but I can know that it all happened - that old Cairo existed, and a particular potter. To have the leaping fish sherd on my mantelpiece - and all those other sherds in the cake tin - expands my concept of time. There is a further dimension to memory; it is not just a private asset, but something vast, collective, resonant. And all because fragments of detritus survive, and I can consider them.
