Janiculum Mills Excavations
Pictures of the 1999 season in progress
27/06/99 - 05/07/99
Removal of modern car-park surface and make-up layers, using precision
archaeological tools - a power drill to break up the indurated surface,
a chainsaw to take down part of the hedge fronting the street, and of course
trowels to clean up last year's trench.
Further cleaning of the deposits over the southern side of the interior
of the mill, just inside the fence, and emptying of the fill of a modern
water-pipe trench cutting across part of the site. A bulldozer came to
remove our spoil heap, which had already colonised much of the car park,
and we began fencing off an area around the driveway to the old car park
entrance prior to commencing excavation there. In the afternoon we ripped
up the San Pietrini cobblestones of the driveway - an exhausting task.
||Erecting barriers around the old entrance to
the car park, preparatory to extending the excavation here - 06/07/99.
||Removing the spoil heap - three lorry loads
already! - 06/07/99.
||... while more cleaning goes on ... 06/07/99.
|| ... and on ... - 06/07/99.
With the cobblestones removed, we began taking off the make-up levels for
the driveway. Almost immediately the tops of what seems to be a late wall
flanking the south side aqueduct channel and a part of the concrete core
of what may be internal walls of the mill started to become visible, a
mere 20-30 cm below the street surface. Meanwhile, clearance of the modern
water pipe trench exposed the corner of the concrete floor of the north-west
room inside the mill.
Further work in the driveway has now exposed the top of the wall flanking
the other (north) side of the aqueduct channel, and much collapsed brick
and tile in the fill of the aqueduct. The modern water pipe trench is now
nearly emptied of its fill, and the foundation trench cut for the mill
structure is visible in its floor.
Rain stopped play around mid afternoon.
||Cleaning in the driveway; the tops of blocks
belonging to a secondary phase flanking the aqueduct are starting to appear,
running diagonally across the picture - 08/07/99.
||Cleaning to expose the tile and brick collapse
overlying the filled-in aqueduct channel. - 08/07/99.
The modern water-pipe trench was completely emptied of its modern fill
and photographed. Removal of modern deposits in the driveway continued,
defining more clearly the tile deposits over the aqueduct channel. With
the aid of two extra volunteers, we began clearing modern deposits over
the internal rooms of the mill, exposing a silty accumulation within the
||Interior NW corner of the mill structure, with
a patch of the floor visible at centre, exposed in the trench for a modern
water-pipe. (Modern concrete in section to right). - 09/07/99.

aqueduct channel. - 09/07/99.
