Kug-tiise (tomb stone / grave monument)

The term kug-tiise (also rendered kug tiise or kugtiise; Mòoré: kug = stone, tiise = burial or grave marker) designates the category of carved laterite and granite monuments that constitute the most distinctive output of the Nyonyosi stone tradition. The corpus encompasses three morphological types arranged roughly by prestige: flat incised stelae as undifferentiated plot-markers; columnar phallic pillars for male ancestors; and figurative monoliths — the rarest type — representing founding matriarchs or tengsoba lineage heads. Pieces were either placed above the burial mound outdoors, serving as territorial anchors and libation surfaces for the community, or deposited within the tomb chamber itself, accompanying the body as a permanent spiritual representative.

The term appears in the Nyonyosi and Mossi-area ethnographic and art-historical literature as the local designation distinguishing these grave-commissioned stone objects from other stone objects in the landscape. Because the kug-tiise tradition was not documented systematically until Roy's work in the 1980s, many specimens reached the Western market under uninformative labels such as 'Voltaic stone figure' or 'Mossi, stone'. Recognition of the kug-tiise as a coherent corpus with internal typological logic — pillar, stele, figurative — is essential for correct attribution, condition assessment, and interpretation of any Nyonyosi stone object in a collection.
