Planet X: Appearance at PASSAGE

The ancients described the passing Planet X as a fire dragon in the sky
or a bird.  Hail and high winds and red dust and volcanic eruptions and
earthquakes and high tides accompany these eipsodes.  In the Mahabharata
Garuda is described as a winged deity which had a radiance like the Sun,
could change shapes at will, and destroyed other gods and kings by
casting down fire and stirring up storms of reddish dust which darkened
the Sun, Moon and stars. Janva-Khanda Nirmana Parva is described as a
fierce fowl with one wing and one eye, which vomits blood.

    All the quarter of the earth, being overwhelmed by 
    showers of dust, look inauspicious. Fierce clouds,
    portentous of danger, drop bloody showers during 
    the night. ... Meteors, effulgent like Indra's
    thunder-bolt, fall with loud hisses ... People, for 
    meeting together, coming out of their houses with
    lighted brands, have still to encounter a thick gloom 
    all around ... From the mountains of Kailasa and
    Mandara and Himavat thousands of explosion are 
    heard and thousands of summits are tumbling down. ...
    Fierce winds charged with pointed pebbles are 
    blowing, crushing mighty trees. In villages and towns
    trees, ordinary and sacred, are falling down, crushed
    by mighty winds and struck by lighting.
        Mahabharata

And Plato documents what occurs during a passage reporting on when the
Greek Solon visited Egypt and an old priest spoke to him:

    You are all young in your minds which hold no store 
    of old belief based on long tradition, no knowledge 
    hoary with age. The reason is this. There have been, 
    and will be hereafter, many and divers destructions of 
    mankind, the greatest by fire and water, though other 
    lesser ones are due to countless other causes. Thus the 
    story current also in your part of the world, that 
    Phaethon, child of the Sun, once harnessed his father's 
    chariot but could not guide it on his father's course 
    and so burnt up everything on the face of the earth and 
    was himself consumed by the thunderbolt - this legend 
    has the air of a fable; but the truth behind it is a 
    deviation of the bodies that revolve in heaven round 
    the earth and a destruction, occurring at long intervals, 
    of things on earth by a great conflagration... 

    Any great or noble achievement or otherwise 
    exceptional event that has come to pass, either in your
    parts or here or in any place of which we have tidings, 
    has been written down for ages past in records that are 
    preserved in our temples; whereas with you and other 
    peoples again and again life has only lately been  
    enriched... when once more, after the usual period of 
    years, the torrents from heaven sweep down like a   
    pestilence, leaving only the rude and unlettered among 
    you. And so you start again like children, knowing    
    nothing of what existed in ancient times here or in 
    your own country... your people remember only one 
    deluge, though there were many earlier...
