The church of S. Maria Maggiore at Bergamo is a valuable specimen not only of this transition in its early stage, but of the culmination of the Romanesque, two centuries later. An inscription on the arch of the portico records that it was founded in the time of Pope Innocent II. and King Lothair II., _i.e._ about 1135, Rogerius being then the Bishop of Bergamo.[135] The builder's name is also recorded as Magister Fredus, probably short for Godfredus. Magister Fredus is not expressly said here to be of the Guild of Comacines, but as his work was entirely in Lombard style, with a few slight indications of a freer school, and as the architects who succeeded him were, as may be proved by documents, Comacine Masters chiefly from Campione, we may fairly make the hypothesis that he too was one of the guild. The little that remains of his work is to be seen in the interior, where the round arch still predominates, and in the exterior walls of the apse, with its crown of arches and colonnettes. The parts due to the later brethren of the guild are the rich ornamentation of the two façades with their grand and characteristic Comacine porches, and also the Baptistery. It was in 1340 that Giovanni, son of Ugone (Big Hugh) of Campione, a _celebre scultore ed architetto_, was commissioned to build this Baptistery. According to the fixed laws of the Comacines he made it octagonal--the mystic sign of the Trinity, being formed of a threefold triangle. Around it entwine circles of arches and colonnettes, some lines having double columns; these reach to the cornice of the roof, which cornice is composed of reliefs allusive to the Sacrament of Baptism.
