Mrs. Geriatrix enjoys her husband's devotion and also her status as wife of the village's most senior inhabitant, which makes her one of the inner circle of village wives. Her youthful appearance suggests that she is less than a third of her husband's age and is also a lot taller. Although as ambitious and gossip-prone as the other wives, she has also shown herself to be very quick-witted. She is an excellent seamstress but has Geriatrix do most of the housework. She rules her home and marriage, and regularly tells her husband what to do even in direct contradiction of his own stated opinions. She does seem to be happily married, however, and the only serious conflict in her marriage is her occasional apparent interest in Obelix which makes her husband insanely jealous. On one occasion, she is offered the magic potion. She does not appear to be interested and says that it's very fattening, while staring at Obelix. She appears to be in favour of women's rights, as shown in Asterix and the Secret Weapon. She eagerly accepted the radical changes in the village that occurred in this story. She and Impedimenta cause a gigantic fight in the short story "Mini Midi Maxi".
She has never been officially named and is always referred to by the local title for wife and the translation of her husband's name (Albert Uderzo has stated she is partially based on his own wife and he wishes to retain an air of mystery). In Asterix and the Soothsayer, Impedimenta appears to address her as Myopia (which, given her choice of spouse would be extremely appropriate), but equally this may have been an invocation to a Gaulish Goddess (of short-sightedness).
