Sculpture of a Woman with Four Children, from Mali, c.1100-1450 CE: this sculpture was created in the ancient city of Djenné-Djenno
Created during the 12th-15th centuries CE, this sculpture depicts a woman sitting cross-legged on the ground, with two children on her lap and two more clinging to her back. Scarification patterns are visible on the woman's temples, and there is a thick, undulating line running from her forehead to the nape of her neck, likely representing a serpent.
As this article explains:
Snakes on Inner Niger Delta sculptures are a common element and should be seen as a positive iconographic component. They represent control of a potentially dangerous benevolent power that must be tamed, domesticated, nourished, and satisfied so it will continue to provide protection.
This is one of the many terracotta sculptures that were produced in Djenné-Djenno, located in the Niger River Valley of Mali, in West Africa; Djenné-Djenno sits just to the south of the Medieval city of Djenné, which is still a major center of Islamic scholarship.
The ancient city of Djenné-Djenno dates back to at least 250 BCE, making it one of the oldest cities in West Africa. For centuries, it also served as one of the largest urban centers/trading hubs in the region, with a peak population of about 20,000 people. The city began to decline in the 9th century CE, when residents (and trade) began moving northward to the nearby city of Djenné, which had just recently been founded by Muslim traders. Djenné-Djenno was ultimately abandoned by the end of the 15th century.
Unfortunately (and unsurprisingly), most of the artifacts from Djenné-Djenno were looted or destroyed by colonizing forces during the 19th-20th centuries. Some of those artifacts have been repatriated in recent years, and there are ongoing efforts to return more of them.
