For they were in three stories] As the galleries were in three heights one above another, so were the chambers between them, and the light that they received was through the galleries on either side. But had not pillars] Neither chambers nor galleries stood upon pillars, as some other buildings in the holy virge did, for then the galleries in the second and third story might have been enlarged, by jutting out towards the courts, and not have trenched upon the breadth of the chambers; but they were all built up with an even wall, only some large openings there were all along the galleries, for the more aire and the better sight.
