Specifically female golden orb-weaver spiders from Madagascar. To get enough silk for the two garments (for there is a brocaded shawl as well as a cape) took nearly eight years but the results are pretty spectacular. That rich golden yellow is the actual colour of the spiders’ silk too.
Garuda (Vishnu’s Mount) Seated in Royal Ease
"Garuda is the great solar bird ridden by the Hindu god Vishnu. In this representation, however, his only birdlike characteristics are wings, the tips of which have been broken off. He sits in the relaxed posture of maharajalilasana (royal ease) and projects a noble and serene presence. He probably attended a statue of Vishnu."
