Ekkehard II (died 23 April 990), called Palatinus ("the Courtier"), was a monk of the Abbey of Saint Gall who became known for his sequence poetry.
About 973 Dowager Duchess Hadwig of Swabia, the widow of Duke Burchard III called Ekkehard II to her seat at Hohentwiel Castle.
Hadwig, a member of the Imperial Ottonian dynasty, was wont occasionally to visit St. Gall, and eventually asked for and obtained the services of Ekkehard as her tutor in the reading of the Latin classics.
Ekkehard was the author of various ecclesiastical hymns, known as sequences, all of which are lost, except one (Summis conatibus nunc) in honour of Saint Desiderius.
His records were the basis for the 1855 historic novel Ekkehard by Joseph Victor von Scheffel, which became hugely successful.
