Little is known about Ango, who was a French draftsman active in Rome in the 1760s. He befriended many young French art students at the French Academy in Rome, although he was not himself a pensionnaire. He most likely supported himself by making red-chalk copies of works by his friends and of paintings in local collections and churches. On this sheet, he copied not a whole composition, but two separate motifs from the Sistine Chapel ceiling. The larger motif on the upper part of the sheet shows the pendentive featuring the Cumaean sibyl, one of the five female prophets depicted on the ceiling. The sketch below is of one of the triangular spandrels, which contain family groups of the ancestors of Christ.
