The origins of a written literature can be found in most of the civilisations of the ancient world; in 
India. China and among the Jewish people, whose great work of literature is the Old Testament of 
the Bible. However, it is the Greeks whose literature is taken to represent the start of Western 
literature. Their greatest single contribution was drama, a form of literature that has continued 
undiminished to the present day. Other literary forms that developed from the time of the ancient 
Greeks and Romans onward have been poetry in its many different styles and forms, the essay, 
biography and autobiography, and the novel. Other types of written work from these periods, 
dealing with such matters as history, philosophy, politics, religion, science and criticism may also 
be classified as literature from the point of view of style.
