Tessomancy



"Well, Harry's got a wonky sort of cross -- that's trials and suffering. But this here could be the sun -- that's happiness. So... you're going to suffer but you're going to be happy about it."

- Ron Weasley reading Harry Potter's tea leaves

Tessomancy (also known as Tasseomancy or tassology) is the art of reading tea leaves to predict events in the future. Tessomancy is taught as part of the Divination course at Hogwarts. In Harry's third year, during one of his Divination lessons, Professor Trelawney read the tea leaves in Harry's cup and saw four things: the falcon, a deadly enemy; The club, an attack; The skull, danger in your path and the Grim, a spectral dog which is an omen of death.

Etymology
The terms "Tessomancy", "Tasseomancy" and "tassology" derive from the French word for teacup; "tasse", and the Greek suffixes, "-graph", "-logy", and "-mancy".
