Technical Observations: The sistrum handle is intact, except for the missing arched portion, and in stable condition. The patina, which is evenly dark brown with small spots of green and red, is relatively thin. Lack of detail appears to be in the casting rather than the result of wear or corrosion.
Except for the tube shape at the bottom, the object is solid cast, probably using a lost-wax process. The lack of fine detail, which appears to be an attribute of the casting rather than its condition, makes it difficult to suggest a direct or indirect process. The object was cast as a single unit with no joins, and the bottom edge is cast, rather than being a broken surface.
