What the sources establish

Procopius reports that in Justinian’s later reign certain monks brought silkworm eggs from the East, enabling imperial sericulture.

Procopius, Wars 8.17, is the source. Britannica independently repeats the Byzantine sericulture tradition with due caution. No silkworm genome dated 552 is offered.

Established: a received story credits Justinian’s reign with acquiring silkworms. Not established: a unique output series, or that the anecdote is a laboratory log.

Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.
