A tool for archaeo-/ethnoastronomical alignment studies.
The ArchaeoLines plugin displays any combination of declination arcs most relevant to archaeo- or ethnoastronomical studies. Of course, principles used in this context are derived from natural observations, and many of these declinations are still important in everyday astronomy.
Some religions, most notably Islam, adhere to a practice of observing a prayer direction towards a particular location. Azimuth lines (vertical semicircles from zenith to nadir) for two locations can be shown. Default locations are Mecca (Kaaba) and Jerusalem. The directions are computed based on spherical trigonometry on a spherical Earth. In addition, up to 2 custom azimuth lines, and up to 2 custom declination lines can be drawn, also with customized labels.
The lunar lines include horizon parallax effects. There are two lines each drawn, for maximum and minimum distance of the moon. Note that declination of the moon at the major standstill can exceed the indicated limits if it is high in the sky due to parallax effects.
It may be very instructive to let the time run quite fast and observe the line of "current moon" swinging between its north and south limits each month. These limits grow and shrink between the Major and Minor Standstills.
The sun likewise swings between the solstices. Over centuries, the solstice declinations very slightly move as well.
