In Ancient Rome, diffarreatio (from Lat dif- + farreum, a spelt-cake)[1] was a form of divorce in which a cake was used.
Diffarreatio was properly the dissolving of marriages contracted by confarreatio, which were those of the pontifices.
Festus says it was performed with a wheaten cake and that it was called diffarreatio from far, "wheat".
Vigenère claims that confarreatio and diffarreatio are the same thing.
