Before the establishment of a regular Observatorj^ a succession of 

 astronomers, more or less famous, made use of temporary accommoda- 

 tions. In the buildings of the old college Clavius made observations 

 with a zenithal sector in 1572, and following years. Sciieinee (•(>!- 

 lected the materials for his famous Rosa Ursina, the printing of wliich 

 was completed in 1030 at the new college, west of the Church of St. 

 Ignatius. There, too, Gottignier and BorCtONDIo made occasional 

 observations. Maire observed the comet of 1844 at tlic English Col- 

 lege. BoscoviCH fixed himself in the principal liall (»f the Kircher 

 Museum. Finally, Asclepi organized a ])ermanc]it establishment in 

 1704; and in 1787 a square tower was built to accommodate the Ob- 

 servatory at the eastern angle of the CoUege facade on via del Gesii. 

 A new building was put up in 1853, having for substructure the enor- 

 mous piles which had been intended to support the dome ot the Church 

 of St. Ignatius.
