Secundus of Non or Trent was an adviser at the court of the Lombard king Agilulf (590–616 CE). He wrote a now lost history of the Lombards (Historiola) which Paul the Deacon used in his Historia Langobardorum. "He seems to have known much about the early Lombard leaders, but very little about how and where the Lombards were settled in Italy." (Paul Fouracre). He died around 612 AD.
