When the plaster dries, the color is literally bonded in. Further touches may be put on a secco, on the dry plaster. The antis believe that some of the darkness of the Sistine ceiling and lunettes was put there by Michelangelo himself, in a dark wash of black pigment in glue size, brushed on after the fresco was dry to give more density to the figures and atmosphere to the space. They think this wash...

The slow drying of the intonaco gave Michelangelo all the time he needed to correct his shadows without having to use the washes of black pigment and glue size that the critics believe to be his handiwork.

The fear that the cleaning has taken off any of Michelangelo's a secco passages seems unfounded. According to Colalucci, these retouchings on dry plaster by his hand have all been identified.

At Mustansiriya University, there are two "committees" representing Shi'ites-radical cleric al-Sadr is particularly popular-and a third is backed by Sunni students. All three routinely celebrate religious events on campus, plaster walls with posters depicting their respective religious leaders and conduct campaigns urging students to adopt "Islamic" clothing and behavior.
