This group of sixteen carved bone pendants is from the Maasai people of Kenya and northern Tanzania.
Each has a pleasing, elongated shape, perhaps based on the shape of a teat, which seems likely given the traditional Maasai dependence on milk in the diet.
Related examples of necklaces with such pendants are illustrated in Grootaers & Eisenburger (2002, p. 322) who report that the Masai traditionally tied such bone pendants with braided leather thongs to rams to protect them against disease and as a fertility talisman.
Traditionally, the Maasai have led a semi-nomadic lifestyle. They were pastoralists and kept cattle and sheep. The Maasai diet consisted primarily of raw meat, milk, honey and raw blood from cattle.
Each pendant here is in fine condition and has a good weight.
