Glossary

Decorated

A distinctive phase of English Gothic which developed at the end of the 13th century and continued into the later 14th; sometimes abbreviated to Dec. Named from its elaborate window tracery, which abandoned the simple circular forms of Geometric in favour of more varied patterns based on segments of circles. Dec tracery makes much use of ogee or reversed curves, which were combined in the 14th century to produce reticulated and flowing tracery composed of trefoils, quatrefoils and dagger shapes. Similar inventiveness is seen in the patterns produced by the lierne and tierceron vaults of the period, in the three-dimensional handling of wall surfaces broken up by canopy work and sculpture and in imaginative spatial planning making use of diagonal axes.

Hammerbeams

In a timber roof, horizontal brackets projecting at wall-plate level like an interrupted tie-beam; the inner ends carry hammerposts, vertical timbers which support a purlin (horizontal longitudinal timber) and are braced to a collar-beam above.
