The Fall of Kāmadeva — An Astronomical Allegory of Warmer Spell.
Quick note to self
Event around 5400 BCE +/- 2000 years
— A huge volcanic eruption occurred on Sumatra (in what is now Indonesia): thought to have released 2800 km³ of ash & pyroclastic material, which is estimated to be at least three times that released by the modern eruption of Pinatubo in 1991 (q.v.) This would have had major effects on the world’s weather for several years, perhaps decades, after.
Event around 5200 BCE +/- 500 years
— Astronomical vernal equinox happening at Ardra nakshatra with aphelion, sun near vernal , i.e., Sun is slow during vernal equinox. This means that when planets are near the Sun in their orbit, they move faster than when they are further away. Thus, Ardra time was experiencing an appearance of more time consumption in completion of Spring.
Event “around” 5000 BCE
— Although it is probably dangerous to put a particular year to an event this far back in history, many researchers regard the period around 5000 BC as the warmest in post-glacial times. (read here)
The above quotes gives an imagery of warmer spells around 7000 years BP (Before Present)
The story of Kāmadeva appears to be a clear allegory of climatic change. The story goes as Rudra-Shiva kills Kāmadeva by burning him into ashes, burns his pushpadhanva, restores Kāmadeva as an invisible living entity. The norther hemisphere was then experiencing harsh and hotter climate during vernal in Ardra- Mṛgaṣīrśa nakṣatra.
Longer and hotter springs — Effect of Apsidal Precession
Spring were harsher and appeared to be longer which must have given the imagery that florals are withering away too faster than at any other point of time in history in northern hemisphere. In todays time vernal and summers are harsher and hotter in southern hemisphere and if one recalls bushfire of Australia such events must had been a very common scene during vernal in Ardra with aphelion conditions. This event was thus recorded as a story of Manmatha-Kāmadeva. J.L. Shastri; G.P. Bhatt writes in Ancient Indian Tradition and Mythology Volume 14: The Garuda Purana Part 3. about Kāma, the presiding deity of the disc was born as Sudarsana. Sâmba the son of lord Krsna was also the incarnation of Kāma. Skanda, the son of Rudra (Shiva) was also Kāma. Sudarsana, Pradyumna, Bharata, Samba, Sanatkumara, and Skanda these six are the incarnations of Kāma. Incarnations of Kāma suggests many cyclic times.
It is the story which will further continue as that Skanda being already present but requested by Six Krittikas to become foster mother to him again which is given in RAM & MBH, giving rise to a speculation of Krittika being a secret cutter of apsidal precession, a lost astronomical calculation among many which is not even found in Suryasiddhanta in a complete way just like precession of equinox’s calculations have a miss in the same text.
Next to the warmer spells “around” 5000 BCE we do get a hint that during 5525 BCE the ocean levels rose too and flooded Dwarka.
Note that I go back to my own video where I have given explanation on an errata for apoapsis and periapsis conditions of Sun and Earth. You can also watch it. https://www.youtube.com/watch?v=sVBdRx0sLTk
So, it appears that we were recording Histories ( climatic, geological, human movements, wars along with astronomy) etc. Bingo!
