The chart

The Ascendant is on the left, and the zodiac runs anticlockwise from it. Tap a planet to read what it is doing.

Where several planets sit within a few degrees their glyphs are spread apart to stay readable. The coloured tick on the ring marks each one's true degree, and every aspect line is drawn from the true position.

Their Astrocartography

Where each planet sat on one of the four angles at the moment Rudolph A. Marcus was born. Tap a line to read what the tradition associates with it.

The birth time is unknown, so this map is cast for noon. The SHAPE of it is right and the whole pattern slides east or west with the real time, so treat the longitudes as approximate.

Ten planets on four angles is forty lines, which is more than the interactive tool opens with on purpose. Draw your own map to choose which planets to show.

Charts are computed from real planetary positions (Swiss Ephemeris) for the recorded moment and place. Recorded times can carry small uncertainties; treat house and ascendant placements accordingly.
