I had also had the privilege since the last 37 years to work on several masterpieces as you can see behind me, but basically to do what? Well, to assess, for example, the state of conservation. See here the face of the Madonna of the Chair that when just shining a UV light on it you suddenly see another, different lady, aged lady, I should rather say.
また私は この37年間で幸運にも 何点かの傑作を研究する 機会に恵まれました 研究の基本的な目的の１つは 保存状態の評価です ご覧のように ラファエロの『小椅子の聖母』の顔に 紫外線をあてると とたんに別の女性が現れます 老婦人と言ってもいいかもしれません
