Note: Owner Information Source
PreColumbian Master; Panama Gold
Note: Object Description
Open back cast pendant of a cougar with thick burnished gold layer on surface and copper alloy underneath.
Note: Owner Accession
Gold plated figurine ornaments from Prov. of Veraguas, Panama, collected y Sr. Juan Gratacos, Panama, and from him purchased (Order no.10987) through Dr.J.A Mason. No data on exact site or conditions of finding. All cast in molds and thinly plated
Note: Research Notes
Accession records specify "no info on site." Juan Gratacos, however, did send Lothrop site info on objects at Peabody from Veraguas.
Note: Condition Review
Fragmentary- Loss of both front feet, parts of ears and backfeet. The tail and two other small sections are present as separate fragments. The gold surface is very well preserved except that corrosion underneath has caused the gold to begin flaking and there are several losses in the gold. Pockets of bronze disease are visible in the base alloy where the gold has flaked off the surface and the Cu-alloy appears very porous in areas. There is no build up of corrosion, however, over the surface of the object. A large patch of dirt is present on the underside near the break in the tail and a resin-like substance is present on the opposite side.
Note: Follow-up Notes
The cross section of the small fragments would be ideal for ESEM-EDS.. It appears to be a thick layer of gold at the surface. Would allow investigation of method of gilding.
