Gemini is rising and the Sun, Venus and Mercury are in the first house. Sun and Venus are in Gemini and quite close to the horoscope but Venus, being combust is very weak; Mercury is close to the second house so not so strong as the presence in the first house let us suppose. The Moon is waning in Aries and she is moving away from the sestile of Venus and applying to the sextile of the Sun and the opposition of Mars. We note also that the lord of the horoscope, Mercury, which is also the lord of the Sun, is in trine with Mars. So Mars is the primary significator of body and Mercury the secondary. Therefore his temperament is choleric. Lets note that Aldebaran, the bull eye, the red star of nature of Mars is rising at the horoscope. The Anonymous says:
When Aldebaran rises at the birth time makes the natives prosperous and very wealthy […] they are by far the most glorious, famous and richest than any other man
Since the lord of the Moon is Mars and Mercury is in trine with Mars, Mars is also the lord of the soul. Mars is in sect since the geniture is nocturnal and so can be beneficial instead than harmful. Mars is in domicile in Scorpio and cadent on the cusp of the VI house. We see therefore that is attitude toward life is very well shown by the influence of Mars which gaves him frank, assertive, goal digger, sharp and sometimes a bit tough attitude.
Mercury is doing the heliacal rising since he is visible but was not seven day before the nativity. Therefore he is the lord of actions since the other fast planets, that are, Venus and Mars are unsuitable because the first one is combust and occidental the second one. Moreover Mars is in trine with Mercury and also in trine with the MC in mundo. So Mars contributes with Mercury as a secondary lord of activities. The lord of Mercury by exaltation, Jupiter, is in sextile and parallel in mundo to Mercury and also in antiparallel of declination with Mars so Jupiter testifies both of them. This configuration fits quite well with his profession as a businessman and manager.
Lets note that Mercury is doing a doryphoria to the Sun since he is the lord of the Sun in Gemini and also Mercury is doing the heliacal rising. Since the Sun is angular and in a masculine sign, that configuration is a sign of a distinguished nativity and great dignity, according to Ptolemy.
The Sun and the Moon are both in aphetical places but the Sun in the first house close to the horoscope is going to rise and so he is strong and the he should be preferred as the apheta of the geniture. On the day of his death the Sun by direction reachs the opposition of Saturn. At the same time Mars by direction reachs the IC and so squares the horoscope. The Sun and the horoscope are in Gemini which rules the upper part of the torso and shoulders where the illness, which caused his death, showed up.
