00:00:04,000 --> 00:00:14,000
The blocks of stone were roughly hewn at the quarry, before being 
transported to the construction site where they were definitively 
cut before being put in place.

1
00:00:14,490 --> 00:00:17,710
This demonstration concerns the cutting of a column pillar,

2
00:00:17,710 --> 00:00:20,670
comparable to the ones extracted from the quarry by Romans.

3
00:00:20,670 --> 00:00:23,960
Following the traditional technique, for which the pencil was not used,

4
00:00:23,960 --> 00:00:26,919
the upper surface is deliberately rubbed

5
00:00:26,919 --> 00:00:29,970
with grass
so that the circle traced with a 

6
00:00:29,970 --> 00:00:32,630
bow compass can be seen.

7
00:00:38,480 --> 00:00:42,060
The corners are then broken away with a heavy hammer head,

8
00:00:42,060 --> 00:00:44,040
and the beginning of the round part can be started.

9
00:01:21,660 --> 00:01:26,280
When the upper part of the cylinder
begins emerging from the massive block of stone,

10
00:01:26,280 --> 00:01:28,620
it is indispensable to clearly define its circular edge

11
00:01:28,620 --> 00:01:32,260
with a sharp chisel
and a small sledgehammer.

12
00:01:57,520 --> 00:02:02,340
The architectural elements are adequately prepared and made lighter

13
00:02:02,350 --> 00:02:05,159
before being transported to the Roman construction sites

14
00:02:05,159 --> 00:02:06,979
where they will be definitively cut.
