‘Codex Corner’: sound

The lines in question from the Colloquies (earnest discussions), referring to spiritual leaders/guides, are these (translated from the Nahuatl):-

Those who observe [read] the codices, those who recite [tell what they read]. Those who noisily turn the pages of the illustrated manuscripts. Those who have possession of the black and red ink [wisdom] and of that which is pictured...

León-Portilla explains:-
’Here is an allusion to one of the chief tasks of the tlamatinime [wise men]: to read and make doctrinal commentaries [what should and shouldn’t be believed] on the codices. With striking vividness and realism, these men are described as “noisily turning the pages of the manuscripts”. Since the long strips of amate paper on which the codices were painted were dry and hard, unfolding them produced a characteristic sound which inevitably became associated with the figure of the wise man.’
