I had heard a lot about the Buddhist artwork collection in Guimet- perhaps the largest in Europe.
What i found fascinating in the Museum Guimet , which i visited last year, were the statues of Buddha from various eras and areas. And all the depictions differ slightly
There was Gandhara ~ 1-3rd c (pic1)
Mathura Buddha-5th c (pic2)
Lalitgiri Orissa-9th c ( pic 3)
Ghantashala, Andhra Pradesh -1-2nd c (pic 4)
The only complaint i have is that captions were mostly in French which became a handicap for me.
