A collage (From the French : coller , to glue, French pronunciation: [ kɔ.laːʒ ] ) is a work of formal art, primarily in the visual arts , made from an assemblage of different forms, thus creating a new whole.
A number of scholars believe that marbling originated in China over 2000 years ago and spread to Japan early as the 12th century, where it is still known as sumingashi.
Marbled paper probably reached Europe along the silk route from the Far East to Turkey , where the process became secretive as marbled papers were cleverly used as forgery(copy, fake)- proof backgrounds for official documents. Returning crusaders(reformers) brought the knowledge of the techniques of marbling to Western Europe where it became popular, especially for book endpapers. Today Venice is the European city most identified with paper marbling.
