Day 16 — petroglyphs + mushroom heads

There is a fair bit of rock art around the world depicting mushrooms (& indeed, even mushroom caused euphoria). This one is in the Arctic regions of Siberia & has particularly interesting carvings of mushroom heads.

The Factoid proves via a google search, other kinds of mushroom head are available.

[Disclaimer: As with yesterday’s entry, this poem was written on the correct day (Thursday) but was unable to get it online owing to backlogs, meetings, & other exhaustions.]

The Pegtymel Petroglyphs
A petroglyph is an image created by removing part of a rock surface by incising, picking, carving, or abrading, as a form of rock art. 

i.
white quartz scratches 
on the faces of over
350 dark stones
fine white lines on
bedrock background
in arctic Siberia 

ii.
arms spread wide
legs slightly bent 
at the knees
humans performing 
a shaman dance
ancient magical ritual

iii.
just your average 
Neolithic art gallery
depicting hunters of bears
whales, deer; sailors; 
traders; artists; &
recreational drug users 

with mushrooms for heads
