A Tibetan 21.6 karat or 90 percent gold butter lamp dating from the Ming dynasty. The stem of the lamp is lobed, and the foot features a two line Tibetan inscription with the date of the lamp. The lamp comes with a copy of lab results certifying its gold content. The base of the butter lamp features two rows of incised Tibetan text reading: "In the year of the Iron Dragon, the venerable King Shakya Od made four butter lamps honoring the mandala of Chakrasamvara. Kowtow worship. Made with fifty taels of gold, enshrined." This lamp appears to have been dedicated by a historical figure named Shakyaprabha or Shakya Od, possibly referring to one of the rulers of the Guge kingdom. Shakya Od was the grandson of king Lobsang Rabtan (d. 1485), and he lived during the latter part of the 15th century and into the early 16th century, ruling from around 1500 to the 1530s. Images of King Shakya Od may survive in frescoes at the Lhakhang Marpo temple near Tsaparang, the royal capital of the Guge kingdom.
