either astrological recurrences are more sparse than i thought or i have a Destiny. according to this ephemeris, the last time all seven classical planets were in the same sign (never mind exact degrees) as at my nativity was during the first peloponnesian war.
relaxing the constraints, within 500 BC and 2500 AD, freeing Mars adds two more dates, freeing Jupiter adds two different dates, and freeing Saturn also adds two. Two of the dates are classical, three are mediaeval and one is in the 21st century
you could make a past life regression religion out of this
to take another view, i have put the four major aspects of my chart (though I have a stellium which means this preserves more structure, and basically just leaves saturn free) and in contrast this recurrs very often – in the past millennium, the recurrence has a mean of 32 years, stdev 29 years, min 2 years, max 132 years. this is the sort of distribution i was looking to find
fixing the stellium in the same sign yields 8 recurrences in the 500BC to 2500AD period, average 306 years, stdev 177 years, min 78 years, max 306 years.
i think this is the kind of pattern i would pick if i were to start a past life regression religion. this seems like a good pace for a person without any special destiny who is just chugging through samsara, alternating between periods of existence between this world and the Other World.
