Tedald (bishop of Arezzo)

Tedald (c. 990 – 12 June 1036), also known as Theodald, Theodaldus, Tedaldus, Tedaldo, Teodaldus,[1] Teodaltus,[1] or Teodaldo, was the forty-third Bishop of Arezzo from 1023 until his death.

He was the second son of Tedald, Count of Brescia, of the House of Canossa, and Willa, possible daughter of Theobald II of Spoleto.

He granted permission for Saint Romuald to found a monastery and a hermitage (eremo) at Camaldoli in his diocese (c. 1024).

Tedald also sponsored the work of the monk Guido of Arezzo, whose treatise on music theory, the Micrologus, was dedicated to him.

The bishop also supported the architect Maginardo, who added to the cathedral during his episcopate and was sent by Tedald in 1026 on a paid visit to Ravenna to study its Byzantine architecture.
