thoth (who became hermes who became mercury) who was both moon and wisdom to the egyptians manifested himself mainly as an ibis - a watery bird a restless creature that could not stop searching through marshy ground with its sickle-shaped beak
so to the christians the bird became a scavenger the worst sinner from whom sins sprout forth and grow sacred ibises have had to learn (like any living body) you can't do a thing in this damned contrary world without someone somewhere tearing out its guts
and if you see two ibises (say) standing together by a river waiting for their friend the moon to appear they do have the stance of a couple of old professors who have said all there is to say about the fraught histories of every species that has got itself a life
not that they disguise their own frailties - any joker could knock their legs from under them - they have such a tenuous touch on earth you'd have to guess their brains were in their beaks which maybe sums up the base nature of wisdom - a glimpse of the innate
shrouded in moon darting through water gasping for its last touch of air in a slithery marsh -somewhere there is a store (a golden sump) of truths all life has gleaned about itself (indiana jones can't find it) the querulous beak of the ibis is our frail best bet
