Historical Note to the Volume of Gabriel's Horn

The volume of Gabriel's horn was first demonstrated by Evangelista Torricelli in $1643$.

The result caused great astonishment at the time, as it was the first example of a solid figure demonstrated to be of infinite extent while also having finite volume.


As Thomas Hobbes put it:

To understand this for sense, it is not required that a man should be a geometrician or a logician, but that he should be mad.
