The temples oriented to Capella and Spica are discussed in the next chapter.
The information given in the present chapter may be completed by a table showing the warning stars available for heralding sunrise about the times when the orientations suggest that the various temples were originally founded.
To prepare this table I have used the precessional globe previously referred to. The results are therefore rough, as the ecliptic has been taken as fixed; but they are useful for the purpose of a reconnaissance. The table shows the stars on the horizon, or near it, at the equinoxes and solstices when the sun was 10° below the horizon. When the star was not exactly on the horizon when the sun was 10° below, its position above or below at that moment is indicated in the table by giving the number of degrees the star was above (+) the horizon or below it (-) at the time.
The dates taken are those most conveniently given by the globe, being those in fact occupied by the pole of the equator at some one or other of twenty-four equidistant points on a circle round the pole of the ecliptic starting from 1880 A.D. as zero.
It will be seen that all the stars referred to in the preceding tables occupied positions of great importance between 6000 B.C. and 2500 B.C., and that there are several southern stars indicated which eventually may be useful in the discussion of the southern temples.

The real precedence of Capella and Spica in temple-building is not shown in the above table, because these stars were not used either at the solstices or the equinoxes.
