The Throne of Memory is a special white-coloured wooden chair. The chair was carved by the Titaness of Memory, Mnemosyne. People who visit the Oracle of Trophonius usually go mad when they receive advice from Trophonius. They need to be made to sit on the Throne of Memory to cure them of their madness. This is also the only way to make them recite the advice in an articulate, coherent manner.
