A tri-looped iron bangle (SF 09-218) made from a continuous round iron rod. A detail of the triple loop is shown, right. The bangle ends are thickened and held together by a wire clasp. The bangle was found beneath a cluster (cluster C) of pottery, which archaeologists interpret as part of a larger shrine feature (clusters A-D) in a metallurgical workshop. It rested in soil about 10 cm below a pedestal-handled pottery lid (NK 09-381) that was part of cluster C. The bangle shows signs of corrosion by rusting. Scale in cm. Width: 10.8 cm. Weight: 26.3 g. Site Ngre Kataa. 16 June 2009.
Two views of a large iron spike (SF 09-174) found as part of a carefully laid set of objects that included an iron disc (SF 09-172) and an iron bangle (SF 09-173), among other artifacts (cluster B). Archaeologists interpret this context as part of a larger shrine feature (clusters A-D) in a metallurgical workshop. One side of the spike (lower image) is rounded in profile. On the opposite side (upper image), the spike has been flattened (right side) and its edges curved inward, perhaps to form a casing for a haft. The spike shows signs of corrosion by rusting. Scale in cm. Length: 16.5 cm. Weight: 52.3 g. Site Ngre Kataa. 10 June 2009.
An arc of orange-red burned features is being revealed by excavations in units 46N 8W and 48N 8W in an area (mound 6) that archaeologists interpret as a metallurgical workshop. To the left (west), the body and base of a large pottery bowl (NK 08-522) has been pedestaled insitu. A number of iron bangles surrounded this bowl (cluster A) as part of a large shrine cluster that extended into adjacent units (where the everted jar rim is visible in the north wall, upper left). The base of this cluster was about 20-30 cm above the burned basins exposed in this photo. To the north of the burned features (forward right of the sign board), a zone of white plaster-like sediment is visible. Far right, archaeologist Abass Iddrisu uses a trowel to expose the contours of burned sediment in an adjacent excavation unit. Red and white scale is two meters in length. Arrow pointing north. Site Ngre Kataa. 16 July 2008.
A boulder used an an anvil stone (GS 09-03) sits insitu, center photo, in an area (mound 6) that archaeologists interpret as a metallurgical workshop. The surface facing the camera is worn flat and smooth from use. Its upper surface shows depressions created by use. Behind this boulder is a flat grinding stone (GS 09-04) with a very worn upper surface. Another boulder (GS 09-02) is visible left (north). Behind it the pedestal base of a pot is visible along the adjacent unit's southern edge. The moistened soil in front of the sign board marked by two orange pin flags marks the find spot of an iron point (SF 09-033). Photo scale along unit edge measures two meters. Arrow pointing north. Site Ngre Kataa. 30 May 2009.
A vertical bank of orange-colored fire-hardened soil abuts a cluster of stones in what archaeologists interpret as a forge feature in a metallurgical workshop. The furnace feature occupied the northwest corner of the excavation unit. In the southern haf of the 2x2 m unit were large boulders used as anvil/grinding stones (GS 09-01 and 09-02). A tree root is visible along the base of the unit's western wall (left). Photo scale by burned feature marked in cm. Arrow pointing north. Site Ngre Kataa. 1 June 2009.
A group of insitu artifacts interpreted by archaeologists as a shrine cluster, located in a metallurgical workshop (mound 6). The cluster included a partial everted-jar rim (center), in front of which (north) was a carefully placed group of iron objects, including a flattened iron disc (SF 09-172) standing on edge, a long spike (SF 09-174) positioned horizontally, on top of which rested a half bangle (SF 09-173). To the right (west) of the jar rim is another iron bangle (SF 90-170). These objects are surrounded by broken pieces of pottery. This cluster (B, 8-10) was part of a larger grouping of objects (clusters A-D) that archaeologists interpret as a shrine feature that capped a metallurgical workshop. View looking south. Photo scale marked in 5 cm increments. Site Ngre Kataa. 10 June 2009.
A group of insitu artifacts interpreted by archaeologists as a shrine cluster, located in a metallurgical workshop (mound 6). The cluster included a partial everted-jar rim (upper right), in front of which (north) was a carefully placed group of iron objects, including a flattened iron disc (SF 09-172) standing on edge, a long spike (SF 09-174) positioned horizontally, on top of which rested a half bangle (SF 09-173). To the right (west) of the jar rim is another iron bangle (SF 90-170). To the right of this, surrounded by moistened soil, the edge of a large grinding stone (GS 09-32) is visible. Surrounding these objects are broken pieces of pottery. This cluster (B, 8-10) was part of a larger grouping of objects (clusters A-D) that archaeologists interpret as a shrine feature that capped a metallurgical workshop. Arrow pointing north, view from above. Photo scale marked in 5 cm increments. Site Ngre Kataa. 10 June 2009.
A slightly curved iron disc (SF 09-172). It was found positioned upright among a carefully placed set of objects in what archaeologists interpret as a shrine feature in a metallurgical workshop. A large iron spike (SF 09-174) and an iron bangle (SF 09-173) sat next to it. The disc shows signs of corrosion by rusting. Its function is unknown, though it may be a tool preform. The disc shows signs of corrosion by rusting. Scale in cm. Width: 10.7 cm. Weight: 89.8 g. Site Ngre Kataa. 10 June 2009.
An area of orange-red burned features has been exposed in excavation units 46N 8W and 48N 8W in an area (mound 6) that archaeologists interpret as a metallurgical workshop. Left, back (west), the body and base of a large pottery bowl (NK 08-522) has been pedestaled insitu. A number of iron bangles surrounded this bowl (cluster A) as part of a large shrine cluster (A-D) that extended into adjacent units. The everted jar rim visible in the north wall of the excavation (upper right) was part of this wider set (cluster B). The base of these clusters was about 20-30 cm above the burned basins exposed in this photo, which were likely associated with metal forging. Center photo, flanked by a photo scale, the round rim of a pottery jar is visible in outline. To the north of the burned features (right, foreground), a zone of white plaster-like sediment is visible. Red and white scale is two meters in length. Arrow pointing north. Site Ngre Kataa. 17 July 2008.
Archaeologist Ben Nutor uses a trowel to scrape soil from around a cluster of objects that archaeologists interpret as a shrine feature (cluster A) in a metallurgical workshop (mound 6). An orange flag marks the location of an iron bangle (SF 08-140), the first of four that were found surrounding the large pottery bowl (NK 08-522) seen partially exposed in front of Nutor. An iron headpan used to carry dirt for screening sits nearby. Site Ngre Kataa. 9 July 2008.
