Prologue eser, Turkish for creation, œuvre, accomplishment, originally refered to a piece of work produced by someone. Today it is mostly used for works of literature, music and art. The following pages contain several outgrowths that could be called eser. Some of them might be eser with a capital E. Others, having come about rather casually, are eser without much ado. eser can also be a tree. At least this is how a gardener used the term, whom we talked to in Vezirhan, the site of a former German tree nursery located along the tracks of the Baghdad Railway.
