What is Tasseography?

Tasseography also know as Tasseology is the art of divination (reading the future) by interpreting the signs and symbols found in a cup (usually a tea cup) after the inquirer has drained a cup of loose-leaf tea or coffee in which the grounds are allowed to float freely. Commonly associated with gypsies and witches but in fact practiced by many people. Tasseograph was at its peak in Victorian England.
