One hundred and seven and four-fifths feet from A and the same distance from K and from B is the centre of the arc AK, and at this point is some ruined masonry which seems once to have formed an altar. Zimbabwe is in South latitude 20° 16′ 30″, and consequently the sun, when rising there at the summer solstice, would bear East 25° South were the horizon level. But Mount Varoma interposes itself between the temple and the rising sun at this time, so that the sun attains an altitude of 5° before its rays reach the temple. Then its amplitude will be more nearly 24°, and a line produced in this direction from the altar will pass across the doorway of the sacred enclosure, where the curve of the wall changes its radius, and, roughly speaking, through the middle of the chevron pattern. The same line drawn in an opposite direction for seventy-three feet would fall on a tall monolith which we there found lying by its well-built foundation. Where the pattern ends at A and B the rays of the sun are nearly tangential to the wall, so that all parts of the wall, and those parts only, which receive the direct rays of the sun when rising at the summer solstice are decorated by this symbolical pattern. The sun’s rays would not fall on the altar at this time, and it seems strange to have an altar devoted to solar worship under the shadow of a wall; but the same objection would apply to every part of the interior of the temple, and we can hardly suppose that the priests at Zimbabwe performed their ceremonies of worship outside of the temple, as some tribes of Arabs do with some stone circles at the present day, neither is there any sign of such ceremonies having been performed on the top of the broad wall. The monolith, seventy-three feet from the altar, was sufficiently tall to receive the rays of the sun when it rose over Mount Varoma, and the shadow of a monolith erected on the wall at K would fall on it at the same time, thus marking with great accuracy the occurrence of the solstice. Monoliths had been erected at intervals along the decorated part, and only on this part, of the wall, and these may have served to indicate other periods of the year in a similar way. Near the top of the great tower, which at present stands thirty-two feet high, there is a dentelle pattern, which may be described as a chevron pattern laid on its side, and which resembles a common Egyptian pattern. This extends partly round the tower, but it is impossible to determine its aspect with accuracy as so much of it has fallen away. It seems, however, to have faced the setting sun at the winter solstice.
