According to the writer Jorge Luis Borges, the idea of the Zahir comes from Islamic tradition and is thought to have arisen at some point in the eighteenth century. Zahir, in arabic, means visible, present, incapable of going unnoticed.

This can be considered either a state of holiness or of madness.
