232. 'And the rainbow round about the throne looked like an emerald' signifies the appearing of these also around the Lord. In the spiritual world rainbows of many kinds appear. They appear of diverse colours as on earth, and they appear of one colour. Here it is one colour, because 'like an emerald' is said. This appearance was around the Lord, because it is said 'round about the throne'. [What is] around Him is also in the angelic heaven. The Divine sphere that encompasses the Lord is out of His Divine Love and at the same time out of His Divine Wisdom, and when this Divine Wisdom is represented in heaven, it appears in the celestial kingdom becoming red like a ruby, in the spiritual kingdom becoming azure like a ligure (cyanus), and in the natural kingdom becoming green like an emerald; everywhere with ineffable splendour and radiance.
