Dave ,
the declination of the sunrise at the winter solstice sunrise around 2500 bc is - 24 and summer solstice sunrise is +24 .
It is when the combination of latitude , altitude, azimuth of the event , combine to produce via the formula for declination ,a declination of +or 24 we know that we have a alignment that would would work for the solstice of the period . Today , because of the change in obliquity the declination would be closer to + or - 23 .5 .
