ARCADE, from the Latin word for bow, is 

 the name given to a series of arches supported 

 by columns or piers. As a rule there is a pas- 

 sageway or promenade behind the arcade, as

 teries where the monks used to gather for 

 recreation and exercise. Such an arcade was 

 what the poet Milton had in mind when he

 High over-arch'd, and echoing walks between.

 the columns, so that the arcade is in reality 

 only a decorative screen. This form is known 

 variously as a blind arcade, wall arcad< 

 arcature. Arcades are also used in the interiors 

 of churches for ornamental railings and simi- 

 lar purposes.
