Quiet field

469

The year was full. This aperture was quiet.

The western Roman state was in its last decade, which is a later frame, not a document. In 469 Sidonius watched the trial of Arvandus, praetorian prefect of Gaul, accused of writing to the Visigothic king. Successor kingdoms, the eastern court, and Northern Wei continued. The aperture does not find an instrument that belongs here.

How we know

  1. Sidonius was in Rome for the trial of Arvandus in 469. That is a dated political fact. The phrase “last decade of the West” is our frame, not his.

    • Sidonius Apollinaris, Letters 1.7. The trial of Arvandus, praetorian prefect of Gaul, in Rome in 469, for correspondence with the Visigothic king Euric. See the record
  • Western imperial remnant under Anthemius / later overlapping reigns
  • Vandal Africa
  • Northern Wei consolidation in north China
  • Classic Maya city politics

The aperture

Quiet. The silence is methodological, not historical.

Regions checked

  • Europe
  • Middle East and North Africa
  • East Asia (Northern Wei, Liu Song)
  • the Americas
  • Africa
  • South Asia

Included / excluded

  • Excluded: Fall of the Western Roman Empire. Conventionally 476. Putting it in 469 would be a miss.
