observing the meridian transits of stars; and did we possess detailed and carefully oriented plans of the temples of Chaldæa and Assyria, there is little doubt that we should find that the meridian had been observed there also. Thus it is evident that the several means which were adopted at Zimbabwe for observing the motions of the heavenly bodies were used in other countries also, and in all cases they seem to have been used for regulating the time of celebration of religious festivals as well as the ordinary affairs of life. Forms of nature worship analogous to that practised at Zimbabwe seem often to have been accompanied in other countries by an observation of the heavenly bodies. It is also worthy of note that the stars which were observed at Zimbabwe seem all to have been northern ones, and the builders of these temples probably acquired the habit of observing these stars in the northern hemisphere. To this we shall refer again. What El Masoudi says of the temples of the Sabæans of Mesopotamia does not, of course, directly apply to the temples at Zimbabwe; but in the plans of those temples one is reminded of the multiform temples which he describes, and of the mysteries involved in some of their architectural features which he could not fathom, for in these temples of Mashonaland there are some curious evidences of design in plan. A glance at the plan of the great temple suggests that the architects had carelessly drawn a great ellipse on the ground and built round it, getting occasionally out of line and leaving occasional doorways; but when one realises the wonderfully careful nature of the masonry, and the great accuracy with which the comparatively rough stones have been laid in regular courses, and been forced to combine to produce regular forms, and when a careful plan of the whole building has been made, then it is seen that what were regarded as careless irregularities in construction are, in reality, carefully constructed architectural features, which doubtless had some religious significance to the worshippers, but whose meaning remains a mystery to us.
