Ere the Err of the Ewe -edited

[vagabond]

Spiraling towards efficiency
The grey sweater vanished,
Yet err had a tendency
To crumble amongst the bushes,
While a predicament flows by;
To lie and weep
Some type of sublime cry,
While I tended my ewe
Ere they disappeared my view,              "ewe" is singular, so wouldn´t it be "it disappeared" ?
Granted to greener pastures
As greenest cannot exist,
Within these boundaries reminisced.

spoiler (can´t be bothered to hide it in a box cos it´s a ridiculously subjective association anyway):
the second line made me remember an instant decades back, when a cow ate my sweater (lilac and, btw, cotton, so no animal was harmed).

more seriously:
your poem is an interesting read, content-wise i think i might grasp L 3/4 and L11/12
the others remain a bit mysterious.
not sure if the use of archaic words instead of more known ones adds to your poem even if they cleverly are similar.

for rhythm i´d suggest for L11/ 12:
"as greenest sadly can´t exist
within these bound´ries reminisced."                             
(...although i am not quite sure if "reminisced" is the right word to describe the boundaries of how green the pastures can get.)
