在藏区信教群众的脖子上或其护身小佛龛“嘎乌”里,常有一些形态不一的小铜饰。佩带者视其为圣物,称为“托加”(藏语的音译,含义为“天铁”)。意大利著名考古学家杜齐在《西藏考古》一书中写道:“我在西藏旅行期间,曾偶然见到过几块这样的实物,但我没能买到一个。因为西藏人把它们看作是灵验的护身符,而不愿意离身,如果他们有幸收集到九块的话,则更为如此”(图1、图2)。 In the Tibetan areas around the neck of the believers or their protective small shrines “Gawu ”, there are often a small number of different shapes of bronze ornaments. Wearers regard it as a sacred object, known as “Toga ” (Tibetan transliteration, meaning “Tiangu ”). In his book “Tibetan Archeology”, Duzzi, a famous Italian archaeologist, wrote: “During the trip to Tibet, I occasionally saw a few such objects, but I did not buy one because the Tibetans put them As an amulet of power, unwilling to leave, and more so if they were lucky enough to collect nine ”(Figure 1, Figure 2).
