Near the south door is the Chapel of Our Lady of seven sorrows, founded in 1516 by Antoine de Montécuto, Margaret's confessor and almoner. A fine painting on a wooden panel, by a Flemish artist, hangs over the altar, and was one of the sacred pictures sent by Margaret from Flanders. On the ground outside the church is a curious sun-dial, composed of twenty-four stones arranged in a huge oval, on which are engraved numbers from one to twenty-four, representing the hours of the day. In the centre of the oval are twelve stones arranged in two rows of six each, bearing the initial letters of the twelve months of the year. In order to tell the time, the spectator must stand on the letter of the current month, and his shadow then falls on the hour of the day, he himself being the index. This interesting dial dates from the building of the church, and was probably made for the use of the workmen. It was formerly placed a little further from the edifice, and composed of tiles, but, as it was in danger of being worn away by the constant traffic which passed over it, Lalande had it moved nearer to the church, and the worn tiles replaced by slabs of stone, but carefully preserved the original size and dimensions of the dial. When Francis I. visited Brou on the 1st of October 1541, he was struck by the unique beauty of the church, though he observed that the white stone of which it was built was too soft to stand frost, and would in time crumble away. Paradin, in his _Chronique de Savoie_, mentions the king's visit:--'Je me souviens aussi,' he says, 'avoir veu descendre le feu roy François, quand il vint à Bourg, qui après avoir veu cette esglise restoit ravy en admiration, disant n'avoir veu ny savoir temple de telle excellence, pour ce qu'il contenoit. Vray est qu'il se print garde (comme il esttoit prince excédant en bon esprit tous les rois de son temps) que ceste pierre blanche, dont est l'esglise bastie, ne seroit de durée à la gelée, pour estre trop rare et tendre. Et s'est trouvé depuis qu'il disoit vray: car long temps après, tombèrent du quarré du clochier aucuns de ses grans bastions ou gargoles, qui conduisent les eaues sur le couvert de l'esglise, du costé des cloistres, chose qui fit grand dommage au bastiment.'
