Flecheln

The term "flèche" in French architecture refers to a spire, particularly a slender one placed over the intersection of a church's nave and transepts. These spires are typically constructed with a wooden framework covered in lead or copper, often featuring intricate designs with tracery and buttresses.12

In metalwork, "Flecheln" is a decorative technique used in engraving. It involves breaking up straight engraved lines into a series of short or long zigzag strokes. This method creates a fuller, broader appearance and makes the design stand out more prominently. This decorative style first appeared in the 16th century and gained popularity in the 17th and 18th centuries.3
