The biography:

Christine avait, sur toute chose, le goût des beaux-arts, ou, pour parler plus juste, le sentiment des arts. Elle fit, en Italie, des collections de médailles, de statues: elle s'occupait de chimie, de physique, de tout ce qui était un élément pour son esprit actif et novateur. ...

English translation (by anonymous translator):

Christina displayed uncommon taste for the fine arts. During her stay in Italy she made various collections of medals and statues. She studied chemistry, natural philosophy, and indeed everything that could feed her active and searching mind. ...
