JUPITER IN THE FIRST HOUSE when well-aspected is a good sign of health and general fortune in life. It gives a good-natured, kindly disposition, a nature which breathes cordiality, honor and uprightness. These people love pleasure, particularly out-of-doors, and are fond of traveling. They have considerable executive ability and are therefore sought for positions of importance and responsibility. There is an inclination to stoutness in later years.
Jupiter afflicted on the Ascendant gives a tendency to self-indulgence, according to the sign wherein he is placed. If in Cancer the person becomes an inveterate glutton and literally makes a god of his stomach with the inevitable result that in the course of years he becomes excessively stout, the liver being particularly enlarged and as a consequence he is subjected to sickness of a serious nature. In Sagittarius it makes him an inveterate gambler who would stake his soul on the toss of a coin. In Pisces he becomes an incurable drunkard, in Scorpio a sensualist of the worst nature and so on with the other signs. It may also be said that whenever Jupiter is afflicted on the Ascendant the health suffers through some corruption of the blood.
