1911 Encyclopædia Britannica/Interlaced Arches

INTERLACED ARCHES, the term for a scheme of decoration employed in Romanesque and Gothic architecture, where arches are thrown from alternate piers, interlacing or intersecting one another. In the former case, the first arch mould is carried alternately over and under the second, in the latter the mouldings actually intersect and stop one another. An example of the former exists in St Peter’s in the East, Oxford, and of the latter in St Joseph’s chapel, Glastonbury, and in the cathedral of Bristol.
