(urth) Hierodules

[b sharp]

I'm pretty sure the  ugly Hierodule masks of F, B and O are an insect, a 
lamprey (fish) and a human leper.  I think Famulimus is the leper.

yep, earthly hierodules, uh praying mantises, have very triangular heads.  
So does Thecla (face anyway).  Perhaps Michael Andre-Driussi also?

Praying Mantises are pretty scary looking up close but helpful to us because 
they eat a bunch of nasty, harmful bugs.  Plus they pray!  Deliberate 
symbolism by Wolfe?
