Uranus in 1st House synastry makes your partner unpredictable at times, and sometimes just brilliant – that’s at least your personal experience, although a lot depends on Uranus’ activity in his or her natal chart.
If Uranus is weak, its falling under 1st House synastry will affect your anticipation of some partner-related zest. But your constant communication with the partner can bring their Uranus to life, and then the partner in your presence will feel sharp energetic outbursts, mental ups and downs, even attacks of inspiration; but there is still quite a long way from this state to true creativity. However, it can be quite easy for you to inspire this or that outrage or eccentric disgrace from your partner: you just need not speak directly (the Sun), but without pressing (Mars) and without persuading (Mercury), but including a sincere personal impulse.
A strong onset of your partner’s Uranus (for example, creative ecstasy) can be a difficult experience for you, and you can feel the mediocrity of your own personality next to such radiating brilliance. Yet you can also feel some of the echo of your partner’s inspiration, which, over time and with inner support, can help you make a breakthrough in your own work, although it will be nothing like what you see in him. In short, under Uranus in 1st House synastry, you can have a great influence on the development of your partner’s genius, whatever it is: he or she will be inspired by your mere presence.
