As with many other Tsa Tsas, the iconographic representation of Vajrapani has changed over time. This is evident in the examples depicted here.
Vajrapani  is clearly the oldest Tsa tsa of this category. It's relatively simple form still bears little resemblance to its later iconography. It was probably created between the 10th and 11th centuries. The following two examples, from the 11th and 12th centuries, also bear little resemblance to later depictions of Vajrapani. A comparison with Vajrapani  from the 14th - 15th centuries makes it clear how the design of the Vajrapani Tsa Tsas has been refined in the subsequent 200 years and how it has gained a the fascinating expressiveness and charisma.
Vajrapani  was created in the 15th - 16th centuries. Although it resembles the later form of the 18th - 19th century, it still clearly shows differences.
The last examples are manifestations of the iconographic representations that can still be found today. Vajrapani Tsa Tsas of the last two hundred years differ only in nuances.
This overview shows the changes of the Vajrapani Tsa Tsas in the period from the 10th to the 19th century
