This astrology trivia quiz has 60 free questions with answers and covers the zodiac from every angle: the twelve signs and their symbols, the four elements and three modalities, ruling planets old and new, the ascendant and the houses, and Ophiuchus, the thirteenth constellation astrologers leave out. It also digs into the history: the Babylonians who first sliced the sky into twelve, Ptolemy's Tetrabiblos, John Dee and Elizabeth I, Kepler moonlighting as a court astrologer, the first newspaper horoscope column, and the astrologer Nancy Reagan hid in the White House. There is a round on the Chinese zodiac and Hindu Jyotisha, and a few questions on the science side: the 1985 Nature test, the Barnum effect, and what "Mercury retrograde" actually is. It works for a horoscope-loving group chat and for the sceptic in it. Difficulty is marked on every question. Every answer has been checked against the Wikipedia articles on astrology, the zodiac and the signs, and each question shows its citation.
