Hōr'o-scōpe, n.

n. [Fr. horoscope, Gr. ὡροσκόπος, observing hours or times, especially, observing the hour of birth, from ὥρα, hour, and σκοπός, observing; σκέπτεσθαι, σκοπεῖν, root σκεπ, to view, observe.] 1. (Astrol.) (a.) An observation made of the aspect of the heavens at the moment of a person's birth, by which the astrologer claimed to foretell the events of his life; especially, the sign of the zodiac rising above the horizon at such a moment. (b.) The diagram or scheme of twelve houses or signs of the zodiac, into which the whole circuit of the heavens was divided for the purposes of such prediction of fortune. The most important part of the sky in the astrologer's consideration was that sign of the zodiac which rose at the moment of the child's birth; this was, properly speaking, the horoscope ascendant, or first house. Whewell.

2. A species of planisphere, invented by Jean Paduanus.
3. A catalogue, or general table, of the length of the days and nights at all places. Hesse.
