The golden age of the Sous was in the seventeenth century during the era of the kingdom of Tazerwalt, when the region enjoyed autonomy and profited from both the trans-Saharan gold trade and the sale of sugar to Portuguese, Dutch and English traders.
This engraved silver central headdress pendant would have been worn in the center of the forehead and then attached to a cloth strap. This one has a faux emerald glass stone set in fine silver. I have converted it to a pin but this can easily be reversed for collectors. This may have had hanging pendants from the bottom which are now missing.
