[1] In Brittany she is widely revered as a patron saint of sick children and those whose birth is overdue.

[2] The legend of Saint Tryphine probably derives from a historical individual who was the wife of the early Breton ruler Conomor.

Tryphine was elevated to the position of a martyred saint, along with her son Tremeur, and there are many churches dedicated to them.

Depending on the version of the myth this is either because a prophecy states that he will be killed by his own son or because he is only interested in his wives as providers of sexual pleasure.

Tryphine escapes with magical aid from the dead wives and gives birth in a forest.

The plot involves Tryphine's evil brother, Kervoura, who schemes to inherit the kingdom from Arthur.

He then accuses Tryphine of murdering her son and uses forged evidence to implicate her in a supposed plot to kill Arthur.
