The Roman quarries at Docimium have been seldom studied to date. A thick layer of
debris covers a large extent of the ancient production area. M. Waelkens noticed several
column shafts and column drums during his 1982 and 1987 surveys, but their dimensions
have not been recorded. 127 The column shafts unused and abandoned in Fiumicino canal
(Rome) do not provide further clues, 128 as only three columns of pavonazzetto are known:
a fragment 2.70 m long and 0.60 m in diameter, two small, well-preserved column shafts
and connected by their quarry coat (heights 3.38 m and 1.25 m, diameter 0.45 m), and a
similar group consisting of four small column shafts joined together in a single marble
block (height 2.40 m, diameters 0.30-0.35 m.). 129

128 A total of 318 unfinished marble items have been found between 1959 and 1989 at the bottom and along
the banks of the Fiumicino canal, the waterway that connects the Tiber River to the hexagonal basin of the
Trajanic harbor. They include unfinished marble blocks, column shafts, drums, slabs, bases, capitals,
basins, and fragmentary sculptures. (Fant 2001, 168; Pensabene 2002a, 27).
