[ WP ] I 'm a medieval farmer with no concept of space . Explain the basics of astronomy to me .

With an audible *pop*, the portal closed behind me in a rush displaced air. I brushed the ashen remains of my scraggly beard off my face - and examined my surroundings with a raised eyebrow - squinting through the pale light of the crescent moon above. No, not a crescent, a partial eclipse. Even as I stared, mouth agape, the edge of shadow moved another minuscule inch across the moon's face. *Astonishing! What wonderful luck coming out at this time! * I thought with an idiotic grin. 
 
 *Looks like a... farm? * I tried to remember the exam questions about ancient survival techniques, the ordered rows of foliage distantly ringing a bell. I sighed. *Never know where you're going to appear, I guess. * 
 
 I spotted a sinuous trail of smoke rising from what appeared to be a wooden dwelling. *Aha! That must be where the master of the farm lives. * With a triumphant raising of the chin, I began the trek to the odd domicile - avoiding the lumps of fecal matter and rotting refuse along the way. 
 
 As I crossed onto the building's outer threshhold some sort of alarm system sounded; *No... Not an alarm, could it be? * The entrance to the dwelling burst open and an actual canine animal came running out. 
 
 *An actual'dog'! * I almost burst out laughing as the beast circled me - yapping incessantly. *I've only ever seen pictures! It's so much more fascinating in person! * 
 
 A wrinkled old man appeared in the pool of light cast by the entrance. `` What you doin out'ere young man!'' He shouted, waving one arm violently at the sky. `` Get inside right quick now, demons be roaming tonight!'' He jerked one and and whistled, `` Here, boy!'' and the dog ran to join him. 
 
 I followed and asked, `` Demons? What do you mean?''. 
 
 The old man looked at me like I was mad, `` The devil's own spawn are out hunting'' and he gestured towards the partial eclipse. 
 
 I nodded in understanding. `` I see, religious superstitions based on astronomic events.'' It took all I had to refrain from smiling as one might to a child. Evidently the man cought something of my sentiments, and he glared at me through countless wrinkles marring his face. 
 
 `` I know you young'uns think you know everything, but the demons are out there, brought by the darkness above.'' 
 
 I shook my head sadly, `` I am sorry to disabuse you of your obviously precious ideology, but the darkness you are referring to is merely the Earth blocking the light of the sun before it strikes the moon.'' 
 
 `` Wha-?'' 
 
 `` Furthermore,'' I continued, `` there are no such things as'demons' - or supernatural entities roaming this night, or any other - they are simply the product of your fear of the darkness and the unknown and such.'' 
 
 I gave him a brilliant smile, happy to have helped him learn something new. 
 
 He slowly turned his head and called inside, `` Honey! Get my pitchfork!'' 
 
 *Uh oh. * I turned and ran for the fields as the crazed dog barked shrilly at my heels - praying my coronal-accelerator had recharged enough for another jump. 
 
 `` You're welcome!'' I shouted back at the pitchfork wielding figure. 
 
 `` And stay out!'' He yelled back. 
 
 *Ah well, every trip is a new adventure as they say. * I thumbed the accelerator and a burst of light lit the night once again - before fading to the dull glow of moonlight.
