Ladder

A ladder is a vertical or inclined set of rungs or steps commonly used for climbing or descending.

A ladder is featured in a Mesolithic rock painting that is at least 10,000 years old, depicted in the Spider Caves in Valencia, Spain.

The painting depicts two humans using a ladder to reach a wild honeybee nest to harvest honey.

Footing occurs when another worker stands on the lowest rung and so provides much greater stability to the ladder when being used.

[9] The anchor point is usually a ring cemented into a slot in the brick wall to which the rungs of a ladder can be attached using rope for example, or a carabiner.

Some sources claim that this stems from the image of a ladder being propped up against a wall looking similar to a gallows,[12] while others attribute it to ancient Egyptian traditions involving pyramids and triangles representing the trinity of the gods, and passing through the triangular shape made by a ladder against a wall was seen as desecration.

[13] In comedic children's media, the image of a character walking under a ladder being the cause or result of bad luck has become a common trope.
