The Grim in Harry Potter's cup

Ronald Weasley: "Right. What can you see in mine?"
Harry Potter: "A load of soggy brown stuff."
— Harry Potter's first attempt at tessomancy[src]

Tessomancy[1][2] was the magical art of reading tea leaves to predict events in the future.[3] Tessomancy was taught as part of the Divination course at Hogwarts.[3][2]

Known readings

"My turn ... There’s a blob a bit like a bowler hat. Maybe you’re going to work for the Ministry of Magic.... But this way it looks more like an acorn.... What’s that? A windfall, unexpected gold. Excellent, you can lend me some ... and there’s a thing here, that looks like an animal ... yeah, if that was its head ... it looks like a hippo ... no, a sheep ..."
Ron Weasley reading Harry Potter's tea leaves[src]

At the start of the 1993–1994 school year at Hogwarts School of Witchcraft and Wizardry, during the first third-year Divination lesson of the school year, Professor Trelawney read the tea leaves in Harry Potter'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. During the same Divination lesson, Trelawney read the tea leaves in Neville Longbottom's cup and commented that it was not good. She asked if his grandmother was well.[3]
