Triangles filled with lines parallel to one of the sides are
TRIANGLES. frequently met with in moustache-lifters, and occasionally the annexed patterns are found: but as a rule the Ainu are not fond of merely straight single lines except for "filling" purposes. These patterns are mostly used on their graves. In articles of every-day use they prefer curves as a foundation of their ornamentations. The lozenge
CHEVRONS. pattern, especially one lozenge inside the other, is a favourite among their geometrical designs; also contiguous and detached circles, chevrons, double chevrons, and triple chevrons. The chevrons are mainly used by them on their graves, and they are invariably enclosed between two or four lines.
The two following patterns are elaborations of the foregoing, but are much more uncommon.
ELABORATIONS OF CHEVRONS. The parallel incised lines and parallel lines crossing each other at right angles are met with again and again in Ainu patterns. More common still is the occurrence of a number of parallel lines meeting perpendicularly another lot of parallel lines without crossing them.
A COMMON PATTERN. Parallel lines have a fascination for the Ainu, as we find them in most of their designs.
