Among the beauties which strike more the admiration of the one who visits Rome, it is the rare beauty of its columns, the clearness of the design either of those storied from the basis to the capital or of the more simple ones, that they be for ornamental use of churches, fountains or buildings or those erected to bestow solemn honor to the great leaders. The most noteworthy examples are the two cockleas of Trajan and of Antoninus.
