Part 5 |

This is one of a series of pages of
Medieval and Renaissance illustrations of traction trebuchets. To avoid
problems with historical interpretation (& copyright!) as much as
possible, I have chosen to use pictures which seem to be plausibly
contemporary with the devices being illustrated. Where ever possible
the original source is cited. I have also tried to avoid what seem to
be obvious fantasy pieces. . |
| No. 17 - Tower-top Trebuchet (II) |
Although another "stylised" drawing, it still shows a stable base of crossed timbers (here represented by the X), an upright support (here, unusually, as a closely-spaced pair of timbers) and a wider frame mounted on top which holds the axle. The axle appears only as an almost invisible thin line (just below the elegant curls at the top of the frame), but the wide beam-end timber (or weight) which carries the pull ropes is obvious. The ropes themselves are drawn as radiating lines.
The drawing from which this is taken appears intended to show the
various types of trebuchets used. For a view of the whole picture Click here.

| No. 18 - Framed Machines |

The first (left) is another section of the Elegant Book of Trebuchets illustration shown above. The other (right) is from an Iranian dish (approx 13th Century). In both cases the motive power is not obvious.
Although I have chosen to place them in this traction trebuchet section, the left image might also be a fixed-weight trebuchet, and the right machine could be a torsion or tension powered weapon.
Information about either of these pictures is welcome.
