The buddha is wearing a crown and is adorned like a prince. The face of the statue has been painted with cold gold in the Tibetan fashion and some pigments have been used to colour his hair and lips.
Same as above.
Because of the vajra or thunderbolt in front of him, one assumes this is a statue of Akshobhya, but it could also be the historical buddha, Shakyamuni (who has dharma wheels on the palm of his hands and the soles of his feet). They both touch the Earth with one hand while holding a begging bowl (often missing) in the other. The painting of the face with cold gold and pigments is typical of Tibet, and may, of course, be far more recent than the statue itself. The petals on the lotus base are flatter and more elongated than in the 12th-13th century, and they curl up at the end. His garment is plain, with a thick hem, and covers only one shoulder.
As from the late 13th century circa, many statues were richly gilt. First, they were fire-gilt then the face was painted with cold gold and pigments.
The lotus base with wide round petals is often seen among Nepalese works.
