 Despite his social rank, Blaesus is a shadowy figure about whom scholars have made numerous sumises.The only fact of Blaesus' life that is certain is that he was a member of the Arval Brethren from at least as early as the year 78 to 91, when a gap in the records begins; when the records of the Arval Brethren resume in the year 101, he is no longer present.This has led some experts to conclude Blaesus died between the years 91 and 101.
