The Apple of Truth was offered by Tamra to King Arthur when he met her in the Street of David in Jerusalem. She made him choose among one simple apple, one healing apple and the apple of truth, which was worth 1 dinar. Having eaten that apple, the Truth Spell of the Seeress made the people of the bazaar spoke the truth to him, opened their hearts and spoke about their troubles and wants. Arthur was tested on acting upon that knowledge.
