When you reach the zenith, you're at the top, the pinnacle, the summit, the peak. Zenith developed from Arabic terms meaning "the way over one's head," and then traveled through Old Spanish, Medieval Latin, and Middle French before arriving in English. As long ago as the 1300s, English speakers used zenith to name the highest point in the celestial heavens, directly overhead. By the 1600s, zenith was being used for other high points as well. The celestial term is often contrasted with nadir, or the point that is vertically downward from the observer (imagine a line going through the earth from the observer's feet and out the other side into the sky). Figuratively, nadir simply means "the lowest point."
