PreColumbian Master; Panama Gold
Note: Object Description
Open back cast double bird pendant with enriched gold surface over heavily mineralized alloy. 2 suspension loops in form of straight bars across open backs. Hooked, open beak. Globular pellet eyes with surrounding ring. Bodies are pyramidal shaped. Birds are joined by plain band where central wing would be. The combined tail is thin and flat. Joins may all be in mold but deep crevices are visible between the bodies and tail and at central join at wings.
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.

Photo neg no. 34637B
Note: Condition Review
Fragmentary. Main section includes both bodies, most of tail and one head. PR beak and eye present as fragments. Missing both wings, and section of PR tail. Depletion gilding still intact except for small loss on PL body and tail that shows black substrate. Also cross sections show mineralized black core. Surface partially covered in green corrosion and powdery pink accretion. Appears brittle. Vertical crack through PL side of tail. Many breaks along edges.
Note: Follow-up Notes
XRF: Analyze body and tail SEM:The broken off eye and head are small enough for SEM. Visible cross sections, however, appear black/mineralized with some shiny coppery material at center. Also- what is powdery pinkish material on surface??? X-Ray:Perhaps X-radiography would help reveal joinery of tail with bodies etc.

Condition: Corrosion
Note: Black-core; Green-surface. Also cross sections show mineralized black core. Surface partially covered in green corrosion and powdery pink accretion
Condition: Coloration
Note: Gold Surface appears gold with some green corrosion. Black is visible underneath surface and at broken edges
Condition: Usewear Toolmarks
Note: Abrasion; Scratches; Many small scratches are present in the shiny gold surface underneath the green corrosion
Condition: Pseudomorphs
Note: None
Materials:
Gold Alloy Note: Surface is shiny gold while broken edges reveal mineralized interior. Green corrosion present indicating Cu alloy.
Technique: Fabrication Method
Cast- Open Back Hammered-Sheet Note: Open back cast. The thin band at the bottom may be hammered as the edges appear sharper and irregular
Technique: Joinery
Note: All cast; Other/Unknown. Crevices between join of body and tail and band between wing. Likely done in cast. Top of tail (where joins with body) has hollow appearance (?)
Technique: Finishing
Note: Polished Surface Enrichment. Surface appears polished/burnished as the front is shiny and smooth while the interior of the heads and bodies appear somewhat pitted and rough. Many small scratches in surface under corrosion may be result of polishing/burnishing
