Gohard or Gunhard was a 9th-century bishop of Nantes, lord of Blain, saint and cephalophore martyr of the Roman Catholic Church.
On the feast day of St. John the Baptist, a month after the defeat of Blain, the Vikings arrived at Nantes.
Gohard was celebrating Mass in Nantes Cathedral before a large audience when the Vikings attacked, killing the priest and his congregation.
[1] Legend says that Gohard picked up his severed head and walked down to the Loire where a boat took him to Angers.
The Romanesque crypt of Nantes Cathedral is dedicated to him, and was redesigned shortly after his canonization to house relics brought from Angers.
