Red Cap (of Witches)
The witches of Ireland used to put on a magical red cap before
flying through the air to their meeting-place. It has been
suggested that witches in various countries may have experienced
the illusion of traveling through the air after ingesting
the ‘‘red cap’’ hallucinatory mushroom amanita muscaria (flyagaric).
In Scotland the red caps were bloodthirsty elves who were
said to live in the castles in the Lowlands. They dyed their caps
red with human blood.
