How big is the asteroid?
La grande mortagne ronde de sept stades,
Apres paix, gueere, faim, inondation,
Roulera loin abimant grands contrades,
Memes antiques, et grande fondation.
The great mountain round of seven stadia,
Afterwards peace, war, famine, flood,
It will roll far away sinking great countries,
Even antiquities, and great foundation.
Line 1: What type of mountain is round? A good reference here is to the burning mountain of Revelations which John describes as being thrown into the oceans – a clear reference to an asteroid or comet [Revelations 8:8]. So it appears we have a meteor or asteroid which AFTER (i.e. the hit) causes war, famines, floods, great countries to be sunk.
Seven stadia equals 4,250 feet (a stadion in Greek measurement was 607 feet). So, if this is the circumference (dividing by Pi) gives the diameter – ~1350 feet, slightly more than a quarter of a mile.
Such an asteroid (given an oceanic impact, as line 3 intimates) would impact with the energy of 130,000 Hiroshima-sized bombs (assumptions: perfect sphere, mainly stony asteroid with density 2g per cubic centimetre, 60 km/sec impact speed – see Paulus for full calculation). As a comparison, this is approximately 600 times the energy of the Tunguska event over Siberia in 1908. However, the impact of 65 million years ago in the Yucatan Peninsula, was likely a body of approximately 6 miles in diameter – having 50,000 times more energy than the postulated asteroid.
As a side note, in his letter to the Governor of Provence concerning the Salon meteorite of 1554 Nostradamus:
- Refers to the Meteorite/ comet as ‘terrifying’ 3 times (cf. X.72).
- Uses the ‘stadium’ measure to indicate breadth in the sky. This refutes some authors insistence that the use of the Greek Stadia MUST indicate Mount Olympus in I.69.
