Before the estubliisLment of a regular observatory a successiou of as- 

 tronomers, more or less famous, made use of tem])orary accommodations. 

 In tlie buildings of tlie old college Clavias made observations with a ze- 

 nithal sector in 1572, and following years. Sciieiner collected the mate- 

 rials for his famous Rosa Ursina, the printing of which was completed 

 in 1030 at the new college, west of the Church of St. Ignatius. There, 

 too, GoTTiGNiES and BoRaoNDio made occasional observations. Maire 

 observed the comet of 1844 at the English colU^ge. Boscovicii fixed 

 liimself in the principal hall of the Kircher Museum. Finally, Asclepi 

 organized a permanent establishment in 17G4; and in 1787 a square 

 tower was built to accommodate the observatory at the eastern angle of 

 the college facade on via del Gesu. A new building was put up in 1853, 

 having for substructure tlie enormous ])iles which had been intended to 

 support the dome of the Church of St. Ignatius.
