Planets beneath the horizon, i.e., placed in the 1st, 2nd, 3rd, 4th, 5th or 6th house, although in the 1st house planets are less affected by this condition since by diurnal rotation they are rising towards the ascendant. When a planet is under the earth it is not visible in the sky; thus this condition describes missing objects that cannot be found, motives that cannot be discovered, facts that cannot be brought to light, and a sense of being buried (as in missing treasure).
