The house at 20 Rue Juiverie was the home of Stephen Grolier, a gentleman of the Duke of Orleans, and dates from 1493. The size of the windows and carved ornaments reflected the wealth of the owners. The mullions on the first floor are very refined; the alley arches slope onto a frieze of sculpted foliage and mythical animals; and the tower of the spiral staircase that leads to the galleries is canted. In 1576, Pierre Duxio, a rich Italian merchant, bought the house and had his crest mounted in the yard: it is a carved figure seated on a throne carrying a Grand Duke clinging to a branch.
