Ardo Smaragdus

Ardo Smaragdus (died March 843 AD) was a hagiographer. He entered the monastery of Aniane in Hérault as a boy, probably as an oblate,[2] and was brought up by Saint Benedict of Aniane. He was ordained a priest and made head of the monastery school.[3]

In 794, he accompanied Benedict to the Council of Frankfurt. and in 814, he replaced Benedict as abbot after the latter joined the imperial court at Aix-la-Chapelle.[3]

Smaragdus wrote a life of St. Benedict of Aniane in 822, one of the most reliable hagiological productions of that period. He himself was honored as a saint at his monastery after his death.[3]
