There are four angles which cut the ecliptic in the shape of a cross; they are positioned at the cusp of the 1st house [ASC], where the celestial horizon and the ecliptic intercept in the East. At the cusp of the 4th house; where the meridian and the ecliptic intercept in the north. At the cusp of the 7th house [DES], where the celestial horizon and ecliptic intercepts in the west and at the cusp of the 10th house, where the meridian and ecliptic intercept in the south.
