The main character of Osip Mandelshtam's 1928 novella Egyptian Stamp is named "Parnok" and was perceived by Parnakh as a derogatory caricature.
In 1934 Parnokh published a Russian translation of a collection of Spanish and Portuguese poets (mostly Marrano Jews) who had been executed by the Inquisition (Parnakh had previously translated the poems into French as well, but the manuscript of this translation had been lost).
