All of them are copies of paintings located in Rome. Later years, death and legacy Pierre Rosenberg described Angos's final years in Rome as half-paralyzed, probably from a stroke. In fact, in 1772, in a letter to the Flemish painter Andries Cornelis Lens, Julien, Ango's contemporary, referred to an attack of apoplexy that had left Ango half-paralyzed (the term apoplexy once referred to what today is called a stroke). Ango depended on the selling of his drawings as his only source of income. He was reduced to living on charity, begging in the streets. Interest for Ango and his oeuvre was renewed when four of his albums came into possession of the Copper Hewitt National Design Museum, Smithsonian Institution. The albums comprise 151 drawings, all executed in red chalk, on an average size of 215 x 148 mm. In these albums, when the drawings are after paintings, they almost never depict the full work, but rather study details. On the other hand, drawings after sculpture usually show the full form. These drawings are valuable in that they record the state of paintings and sculptures in Rome in the late 18th century. Further, they may depict Roman sculpture and paintings now lost; despite diligent search, only half of the subjects depicted in Ango's oeuvre have been identified. However, there is no known original composition by Argo, as all his extant drawings are after opera by other artists. Ango's personal drawing style has only recently been recognized. For a long period after the eighteenth century, his drawings were attributed to Hubert Robert, whose drawings Ango copied and whose counterproofs he drew over. Ango habitually signed his drawings H. Roberti (H for Hannibal, his nickname) and Roberti for Robert, his last name. His drawings were (and still are) confused with those of Robert, many of them being signed "Roberti." Over the past few decades, drawings in the collections of various museums, such as Harvard's, have been reattributed. However, many of Robert's drawings, in particular those at the Louvre, remain contested.
