What it is

The mark first appears in Pietro Bembo's 'De Aetna', printed by Aldus Manutius in Venice, as an intermediate value between the comma and the colon.

In 1561 Aldus Manutius the Younger formalised its use in 'Orthographiae ratio', describing it as an intermediate value between the comma and the colon.
