Timelines are displays of a list of historical events in date order, typically a long bar labelled with dates in parallel.

They became popular after 1765, when Joseph Priestley, best known as one of the discovers of oxygen, published A Chart of Biography as an educational resource for students of history. Cartographies of Time by Daniel Rosenberg and Anthony Grafton is a comprehensive history of timelines and other graphic representations of time.
