Technical Observations: The patina is reddish brown and covered with areas of green. Losses at the front edge and at the top are due to the mineralized condition of the head, but most surface detail is well preserved.
The head was cast by the lost-wax process. A circular opening (17 mm wide) at the bottom is sealed with a brown wax. The wax appears to be contemporary with the surrounding corrosion products and could be an original seal. The regular shape of the opening and the thickness of the walls of the surrounding metal probably indicate that the interior surfaces do not match the contours of the exterior and that the original wax model was shaped directly over a prepared core. A 1-mm step in the metal surrounding the hole appears to be the result of adding a flat ring of wax to the area surrounding the hole to add thickness to the base. The incised lines in the face and hair are very crisp. They appear to have been made in the wax model but were probably finished by cold working.
