In practical matters relating to the use of images, as opposed to their theoretical place in theology, the Libri Carolini were at the anti-iconic end of the spectrum of Catholic views, being for example rather disapproving of the lighting of candles before images. Such views were often expressed by individual church leaders, such as the famous example of Saint Bernard of Clairvaux, although many others leant the other way, and encouraged and commissioned art for their churches. Bernard was in fact only opposed to decorative imagery in monasteries that was not specifically religious, and popular preachers like Saint Bernardino of Siena and Savonarola regularly targeted secular images owned by the laity.
