|Royal Style: 45 Degrees|
|Adornment Style <page 2>|
At top left we see the decorative end of an ivory hatpin. It shows four faces, each getting smaller as you go up. But it is not just a change in scale. There is a precise geometric pattern underlying this sculpture. Can you discover its secret?
Here is a hint. A similar design theme was used to create the Mangbetu style of personal adornment. The photo on the lower right shows a Mangbetu hair style, popular during the time that this carving was created (about 1914). The chief is wearing an ivory arrow pin that points along the horitontal (0 degrees). He has another ivory pin ending in a disk that is at 135 degrees from the arrow pin. The top knot in his hat is at 90 degrees from the disk pin. What do 90 degrees and 135 degrees have in common?
