FEWKEs] ANTIQUITIES OF MESA VERDE NATIONAL PARK 33 



one in which the figure-coils follow the direction of the hands of the 

 clock (dextral) ; the other, in which they take an opposite direction 

 (sinistral). The outer end of the volute may terminate in a triangle 

 or other figure, which may be notched, serrated, or otherwise modi- 

 fied. A compound sinistral volute is one which is sinistral until it 

 reaches the center, when it turns into a dextral volute extending to the 

 periphery. The compound dextral volute is exactly the reverse of 

 the last-mentioned, starting as dextral and ending as sinistral. If, as 

 frequently happens, there is a break in the lines at the middle, the 

 figure may be called a broken compound volute. Two volutes having 

 different axes are known as a composite volute, sinistral or dextral as 

 the case may be. 



The meander (fig. 10) is also important in Spruce-tree House or 

 Mesa Verde pottery decoration. The form of meander homologous 

 to the volute may be classified in the same terms as the volute, into 

 (1) simple sinistral meander ; (2) simple dextral meander; (3) com- 

 pound sinistral meander; (4) compound dextral meander; and (5) 

 composite meander. These meanders, like the volutes, may be ac- 

 companied by parallel lines or by rows of 

 dots enlarged, serrated, notched, or other- 

 wise modified. 



In some beautiful specimens a form of 

 hachure, or combination of many parallel 

 lines with spirals and meanders, is intro- p^ iq Meander, 



duced in a very effective way. This kind 



of decoration is very rare on old Hopi (Sikyatki) pottery, but is 

 common on late Zuiii and Hano ceramics, both of which are probably 

 derived from the Rio Grande region. 



Lines, straight or zigzag, constitute important elements in Spruce- 

 tree House pottery decoration. These may be either parallel, or 

 crossed so as to form reticulated areas. 



Along these lines rows of dots or of triangular enlargements may 

 be introduced. The latter may be simply serrations, dentations, or 

 triangles of considerable size, sometimes bent over, resembling pointed 

 bands. 



Curved figures are rarely used, but such as are found are charac- 

 teristic. Concentric rings, with or without central dots, are not un- 

 common. 



Rectangles apparently follow the same general rules as circles, and 

 are also sometimes simple, with or without central dots. 



The triangle is much more common as a decorative motive than the 

 circle or the rectangle, variety being brought about by the difference 

 in length of the sides. The hourglass formed by two triangles with 

 one angle of each united is common. The quail's-head design, or tri-
