Herman of Carinthia, also called Hermanus Dalmata or Sclavus Dalmata, Secundus, by his own words born in the "heart of Istria", was a philosopher, astronomer, astrologer, mathematician and translator of Arabic works into Latin.

Peter the Venerable, also known as Peter of Montboissier, was the abbot of the Benedictine abbey of Cluny. He has been honored as a saint, though he was never canonized in the Middle Ages. Since in 1862 Pope Pius IX confirmed his historical cult, and the Martyrologium Romanum, issued by the Holy See in 2004, regards him as a Blessed.
