In 1999, a hidden library was found in Nesar Temple at a remote village of Bicher in Dolpo, Nepal. It contains more than six hundred volumes of Tibetan manuscripts, ranging in data from the late 11th to the early 16th century. Among them some sixty volumes contain historical prefaces and more than one hundred volumes have beautiful illuminations of the scenes from the life of the Buddha and episodes from the Prajnaparamita (Perfection of Wisdom) texts. By studying these texts within and examining the styles of the manuscript illuminations, Amy Heller was able to shed light on the lost history of this remote Tibetan enclave, the spread of Buddhism int he Himalayas and its artistic legacy.
