I want to know the answer to the following question:
By tradition, what notable figure came to Nepal 250 years before the birth of Christ?
All the background I'm provided with is that "These art and architectural edifices encompass three major periods of evolution: the Licchavi or classical period (500 to 900 AD), the post-classical period (1000 to 1400 AD), with strong influence of the Palla art form; the Malla period (1400 onwards) that exhibited explicitly tantric influences coupled with the art of Tibetan Demonology.". Is that enough to answer the question?
Answer: no
