HYDRAULIC SAW


Codex Atlanticus f. 1078 a-r

Dimension: CM. 201 X 129 X 203

Description: Water as motive power is one of the basic principles of technology before, during, and after Leonardo Da Vinci’s age, up until fairly recent times.

ARCHIMEDEAN SCREW


Codex Atlanticus f. 26 v.

Dimension: CM. 60 x 75 x 15

DIVER


Codex Arundel f. 24 v.

Dimension: CM. 60 X 60 X 15

Description: If there should still be any doubt Leonardo's inventiveness, the study of the diver shows how he was ahead of time; he applies two tubes with a membrane to the mask so that one is for inspiring and the other for exhaling. One tube wouldn't be enough because it would fill up with carbon dioxide and suffocate the diver.

FLOATING SKIS


Codex Atlanticus f. 26 r.

MOVABLE BRIDGE


Codex Atlanticus f. 855 r

Dimension: CM. 60 X 60 X 108

DREDGER


Manuscript E f. 75 v.

Dimension: CM. 60 X 60 X 122

Description: Using man's strength but even that of water, this model's paddles dig the bottom of the channel and clean it. The dredger had a sort of pontoon behind itself in order to discharge mud and the waste picked up.

LIFEBUOY
