Gisela, Abbess of Chelles

Gisela (757, Aachen, Cologne, North Rhine-Westphalia, Germany[1] – 810–11, Chelles, Seine-et-Marne, Île-de-France, France) was a Frankish princess and abbess.

[2] Early in life GIsela was betrothed to Leo, son of Byzantine Emperor Constantine V, but the contract was broken.

"[3] Other correspondence which hints at a friendly relationship is a letter written to Gisela between 793 and 796, where he thanked her warmly for the gift of a hat.

In September 798, he writes to her from his monastery at St. Loup de Troyes, where he laments that an acute fever has stopped him from travelling to see her.

[6] The specific year of her death is unknown, but she died between 810 and 811 AD in Chelles, Seine-et-Marne, Île-de-France, France, in the convent she had served for most of her life, aged between 53 and 54.
