8. (Julia K. Murray, 1982) Compared to Neolithic bangles, F1917.58 has sharper, more crisply defined edges and a glossier polish. Furthermore, the thickness of the wall and the diameter of the hole show only very slight irregularity. The bangle is unusually wide, suggesting that perhaps material from within its circumference was used to make some other artifact. For a discussion of bangles, see Folder Sheet F1917.387.
