Describe + give scale + composition point
Point (1): Zoomorphic sculpture
Reasoning (1): Depicts undulating/stylised snake with two symmetrical heads.
Point (2): Small scale and demonstrates a closed composition
Reasoning (2): Since its original function was both piece of jewellery worn on ceremonial occasions as a pectoral, hangs from neck.
Reasoning/Effect: Therefore, not ‘in the round’ as was only designed to be viewed from one POV.
HOWEVER Additional - depicted scary - Priests possibly wore it when sacrificing individuals. Shows Aztec's power. Deities can be scary. Jaws open, teeth showing.
