As per picture text (Note: date is correct, but time is not correct). The superimposed picture is a screen-shot from video of the moment of sunrise, taken within the model. The scale used is a quadrant divided by 90. Adjustment is needed since Spring has 92.8 days.
Updated. The added lower picture offers an explanation to the metaphorical meaning of the figurines. An allegory between human reproduction and vegetative reproduction. Central to meaning is the plow that penetrates the Earth (or the Earth Mother) to sow the grain seed in the furrow, thus impregnating the Earth, rendering it fertile.
Updated pic. Look at the curious imagery (in red circle), it is key to the allegory that the picture imparts. The fertilisation of Mother Earth in personification. The statuettes are a central feature in a very ancient mythical story, but meant to represent cereal cultivation.
One of several such statuettes, this one dates to pre 3200bce. Not symbolic of cult, but is a science of the cereals, their genetic development, and their cultivation. Also a form of ancient myth-like folklore that in its many subtle changes survives to this day.
Megalithic structure, originally considered as cult temples due to their close links to what seemed cult figurines. Their connection to the biological grain/cereal cycle (see ‘The Two Queens’) hinted at a calendar function. Book relates the search to discover how they worked, how their design evolved technically, and the anomalies that became evident.
Results of tests of both early and later designs prove their functionality and surprising accuracy (see elsewhere on this site).
This is the later and improved method used as a calendar to follow the solar year through the seasons. Shown here is another calendar, and an easy method of telling the time of year, and forecasting accurately the solstice day and time. Measuring movement over some days makes for a more accurate forecast.
Ggantija North is adjacent to an older calendar, both having nearly same orientation. However the equinox to solstice angle in the later unit is 18deg, as against a previous 23deg in the older one. Reason for building a second unit on same orientation. Date: just after ~3550bce.
This is an early form of calendar, one of several, and key to understanding purpose and function of these megalithic structures. Based on optics of the ‘eye’, nature’s ‘camera obscura’. Translates ~sinusoidal movement of object/shadow to a linear movement – easy to tell time of year, except near solstices. Later modified to new method with better forecasting of date (see Ggantija N), and time of solstices. Lat 35.8N
The ‘field of view’ is limited to 18degrees, the equinox to solstice angle, giving a clear indication of Earth’s obliquity at the time of build. Corroborate G F Dodwell’s claim.
This is the later of two units at this site. The early one is pre 5200bce, the other post that date. Dated according to proxies -see other pics-.
Dating events from various proxies, and comparing to calendar design changes and alterations. These indicate Earth obliquity changes between 7000bce and 2000bce. (Note: viewing angle is equinox to solstice of horizon sunrise point, at latitude 35.8 deg N).
Calendars need to be axially aligned to equinox sunrise point on horizon. At ~5200bce and then at ~3200bce there are changes of axial orientation, always ACW, indicating major cataclysmic seismic events.
