Am-Boro Ma-Sar [the house of stones]
Small shrine or pavilion in a village in which a number of fist-sized stones are kept that represent deceased prominent members of the community. Offerings are made, libations are poured and prayers made to the ancestors of the community at this shrine.
- F.J.Lamp, 'House of stones: memorial art of fifteenth-century Sierra Leone', The Art Bulletin, 1983, 65/2, 219-237. [Gives a good description of am-boro ma-sar which is quite separate from his controversial main thesis, that the Temne were responsible for the ancient stone sculptures called nomoli that are found buried in the soil in south-eastern Sierra Leone.]
