Joggled lintel above front door at Conisbrough Castle, Castle Hill, Conisbrough, Doncaster, South Yorkshire, England, ca., 1180. Constructed by fifth Earl of Surrey, Hamelin Plantagenet, half brother of King Henry II.
Joggle, Joggling: Masons’ terms for joining two stones in such a way as to prevent them from slipping or sliding, by means of a notch in one and a corresponding projection in the other. It is often seen exposed on the face of a flat arch. If a joggle is concealed, it is called a ‘secret joggle.’
Turbah al-Farnathîyah, Damascus, exterior, joggled relieving arch, ca. 1224. Mausoleum for Hanbalî shaykh and ascetic, `Alî al-Farnathî.
NOTE: Were I to psychoanalyze myself, I would say that posting these images indicates a strong desire for coolness and stability, qualities I find are in short supply these days. But I don't go in for that sort of thing.
The words “joggle” and “joggling” suggest rough, forceful motion, however. Odd.
