Who did the ceiling decorations in Courtauld Gallery, Somerset House?

Hello guys doing a little analysis, making an attempt to hyperlink the decorators/artists to the completely different rooms in Courtauld Gallery. The uploaded image is within the Blavatnik High quality Rooms of the gallery and I’m stuggljng to seek out the particular particular person and even artists that designed this. The closest I’ve discovered to be talked about are Giuseppe Ceracci, Giovanni Battista Ciptiani and Angelica Kauffman. By any probability does anybody know which artist did this ceiling within the {photograph}? I’ve searched deep into the web however I appear to be unsuccessful… (I don’t have time atm to go to the gallery once more this week therefore reddit submit) Thanks !
