As you may have noticed I think the work of conservators is closely aligned with the humanities, more closely actually than with the sciences or engineering.
T. S. Eliot speaks to the fragility and skill needed for our work when he presents the past as an accumulation of dust that should be appreciated and preserved:
Dust in the air suspended
Marks the place where a story ended.
Dust inbreathed was a house-
The walls, the wainscot and the mouse,
And in a lighter vein, the anonymous song I posted previously celebrates how specialists, tinkers in this case, can do better work than their owners:
Have you any work for the tinker, brisk maids?
Old brass, old pots, old kettles.
I'll mend 'em all with a tink, terry, tink
and never hurt your chattels.
