Term: Grand Cross

DEFINITION:
When four or more planets form two sets of oppositions that combine to form four squares, there is a grand cross or grand square. These planets are also usually related by mode (Cardinal, Fixed, or Mutable). This is a difficult configuration, and may produce more frustration than the T-square, but there is usually great strength accompanying it to endure and develop character.
