I believe you are probably right about that. I hadn't noticed the wings at first.
Geoffry, the lion (singa) in Bali has Hindu-Buddhist origins. In Hinduism, the lion is an avatar of Vishnu. The Buddha sits upon the lion as a throne and it symbolizes the freedom and fearlessness of wisdom.
I have also read that the lion was associated with the Kshatriya caste. At least it is in Indian Hinduism.
