Where in the world your Sun and planets were rising, setting and overhead at the moment you were born.
At the moment you were born the Sun was rising somewhere, setting somewhere else and standing overhead along one line of the globe. The same is true of the Moon and every planet. Drawn on a map of the world, those lines are your astrocartography.
It starts at its quietest — your sign, the world as a field of dots and the Sun’s four lines — with the cities each line passes listed underneath. Add the other planets if you want the whole sky.
