Technical Observations: Much of the surface is covered with thick green corrosion products over cupritic red, with brown oxidized metal in smaller worn areas. The figurine has been heavily worked over, the green layer scraped down and then saturated with a shiny, resinous material. The structure of the piece is sound; the tang beneath the base seems to be incomplete.
The solid figure was cast by the lost-wax process in one piece with its flat base and tang. The details of the face, the uraeus, crook, and flail were modeled directly in the wax. The heavily corroded condition of the surface and subsequent cleaning make it difficult to tell how much the surface was finished, and what amount of detail was lost. The crudely formed low representation of Isis on the figure’s back looks as if it had been carved out of the back rather than modeled onto it. The surface condition also conceals evidence of whether the two small suspension loops were cast with the figurine or joined to it later.
