köken: From in + nuce, the ablative singular of nux (“nut”): literally, “in a nut”. Derived from an anecdote in Pliny the Elder, who ascribes to Cicero the claim that the whole Iliad was once written on parchment and enclosed within a nutshell (Naturalis Historia 7.21.85).
[…] adeoque sola eruendas ratione, in nuce, quod dicitur, aut velut in tabula depictas, simul exhibeam.
