The bell described is an ancient copper alloy artifact with a looped strap handle and a spherical clapper, cast using the lost-wax method and attributed to the 'Lower Niger Bronze Industry' style, a term coined by William Fagg in 1959. It resembles a human male head with notable facial features and frog depictions around the neck, likely part of shrine paraphernalia. The 'Lower Niger Bronzes' category includes diverse copper-alloy objects distinct from the major casting centers of Benin, Ife, and Igbo-Ukwu, with limited analysis and provenance details. The Igbo-Ukwu bronzes, discovered in 1938 and dated to 850 CE, represent the earliest known bronze casting in the region and the earliest copper alloy art in Sub-Saharan Africa, produced using the lost wax hollow casting technique.
