Euclidian but not (NGC 2276)

Cross dimensions four
I steered my faithful ship.

With sea of time 
both aft and fore,
O’er space my hull did skip,
Toward sands of unknown
distant shore.

For ever east, 
where west is west 
Whilst  on a circumferential plane. 

Chart tangential of the 
axial twain
To plow through spatial
 trough and crest  
Of a boundless 
celestial 
ancestral plain, 
Where perhaps
 we shall meet 
again.
