Herodotus also mentions that in 492 BC, some Thracian Brygoi or Brygians (Greek: Βρύγοι Θρήικες) fell upon the Persian camp by night, wounding Mardonius himself, though he went on with the campaign until he subdued them. These Brygoi were later mentioned in Plutarch's Parallel Lives, in the Battle of Philippi, as camp servants of Brutus. However, modern scholars state that a historical link between them and the original Bryges cannot be established.
