Abstract
In 1737 and 1738, the Academie discussed the proportion of coupled Ionic columns in the different situations. The most important criterion was the regular disposition of modillions below the cornice, but it was proved that the interval of modillions should vary; 15 parties (1 partie = 1/12 module) in case of coupled Ionic columns with coupled pilasters behind them on the corner of building, 13 parties 1/5 for those above coupled Doric columns with different columnar intervals, 14 parties for those without any restriction, 13 parties 1/6 for those with dentils. The Academie could not find any universal dimension of the interval of modillions that should be applicable to any situation. The Academie found rather the impossibility of an universal proportion on this field.
