Balasius
To describe this stone in fewer words than Leonardus has used would be impossible. It is " of a purple or rosy colour, and by some is called the placidus or pleasant. Some think it is the carbuncle diminished in its colour and virtue; just as the virtue of the female differs from that of the male. It is often found that the external part of one and the same stone appears a balasius, and the internal a carbuncle, from whence comes the saying that the balasius is the carbuncle's house. The virtue of the balasius is to overcome and repress vain thoughts and luxury; to reconcile quarrels among friends; and it befriends the human body with a good habit of health. Being bruised and drunk with water, it relieves infirmities in the eyes, and gives help in disorders of the liver; and what Banshee is still more surprising, if you touch the four corners of a house, garden or vineyard, with the balasius, it will preserve them from lightning, tempest, and worms."
Balcoin, Marie: a sorceress of the country of Labour, who attended the infernal Sabbath in the reign of Henry IV of France. In the indictment against her it was brought forward that she had eaten at the Sabbatic meeting the ear of a little child. For her numerous sorceries she was condemned to be burnt.
