Tarot cards

"The Headmaster has intimated that he would prefer fewer visits from me. I am not one to press my company upon those who do not value it. If Dumbledore chooses to ignore the warnings the cards show. Again and again, no matter how I lay them out - the lightning-struck tower, Calamity. Disaster. Coming nearer all the time ..."

- Professor Trelawney speaking to Harry about the warnings she saw in the cards

Tarot cards are used in the art of Divination, specifically the field of Cartomancy. During the 1996–1997 school year Sybill Trelawney was making frequent visits to Albus Dumbledore's office to tell him about the bad omens she was seeing in the cards. She also attempted to consult with Firenze regarding this matter, but he apparently knew nothing of cartomancy and seemed to find her "comical."

There was a healer in Diagon Alley who sometimes consulted what may have been tarot cards.
