There are two other places where the meridian transits of stars have been watched at Zimbabwe, and in these cases it is still the same portion of the heavens which has been observed. The altar in the eastern temple in the fortress has been placed ten feet E.S.E. of the centre of the arc, in order to permit of the meridian being observed through the gap in the rock which formed the northern doorway. Here the line laid off is much shorter than that between the rock and the great temple, but still fairly accurate observations could be made. To the north of the centre of the arc of the great wall of the western temple there is, as we have already shown, a great monolith erected, and at one side of this the stars might be observed at their culminations. As seen from the altar this monolith would mark out an angular distance of 9° of the meridian. It is remarkable that only stars of the northern hemisphere seem to have been observed at Zimbabwe, for in the great temple itself the culminations of southern stars could quite as easily have been observed as those of northern ones, and in the fortress all view of the northern sky is almost completely shut off by the cliffs and huge boulders which form its northern line of defence; yet every point from which northern stars could have been observed has been used for this purpose, and there is no temple there from which northern stars were not observed, while at the same time the openly displayed southern sky has been left unregarded. This, of course, points to a northern origin for the people, and suggests that before they came to Zimbabwe they had acquired the habit of observing certain stars—a habit so strong that it led them to disregard the use of the southern constellations, though they must have known that they would equally well have served to regulate their calendar; it even seems to indicate that they attached ideas of veneration to certain stars, and rendered them worship. It seems a plausible supposition that while the great temple itself was devoted to solar and analogous forms of worship, the little circular, or partly circular, temples within its walls, of which we found one fairly well preserved and fragmentary remains of several others, were dedicated to the cult of particular stars.
