Witham and the surrounding area of central Essex has a long history. There are old defensive earthworks at Chipping Hill, and remnants of Mesolithic, Neolithic, Bronze Age, Iron Age, Roman and later occupations have all been documented in the area (see, e.g., Rodwell, 1993; Gyford, 1999).
2. The flint: Local flint cobbles exhibit a range of grey to black tints when fresh, below the mm-scale white weathering rind (`cortex'). It is readily available in local fields and gravel pits, and would have been an immediately attractive choice as a building material. It is very hard, yet sufficiently brittle that it breaks with moderately flat faces and a signature conchoidal fracture. This cobble, spied low in the church wall, is fractured, with a waxy sheen, a bluish surface colour (not unusual in flints) and a thin channel, possibly a relict burrow (`trace fossil') in the former sea floor.
