There is no document of civilisation which is not at the same time a document of barbarism. And just as such a document is not free of barbarism, barbarism taints also the manner in which it was transmitted from one owner to the other. 

Benjamin, W (1940) Theses on the Philosophy of History 

To have a souvenir of the exotic is to possess both a specimen and a trophy; on the one hand the object must be marked as the exterior and foreign, on the other it must be marked as arising directly out of an immediate experience of its possessor. 
The actual locale of the souvenir is often commensurate with its material worthlessness: the attic and the cellar, contexts away from the business and engagement with everyday life. Other rooms of the house are tied to function (kitchen, bath) and presentation (parlour, hall) in such a way that they exist within the temporality of everyday life, but the attic and the cellar are tied to the temporality of the past, and they scramble the past into a simultaneous order which memory is invited to rearrange: heaven and hell, tool and ornament, ancestor and heir, decayed and preservation. The souvenir is destined to be forgotten; its tragedy lies in the death of memory, the tragedy of all autobiography and the simultaneous erasure of the autograph.
