Specimens of ancient oracular and fighting eolipiles : with remarks on dragons and other fire breathing monsters of mythology and the Middle Ages, being a supplement to his treatise on hydraulics and mechanics
An 1845 New York supplement by mechanic and hydraulics writer Thomas Ewbank, collecting woodcut specimens of ancient oracular and fighting eolipiles, or steam-powered fire-breathing monsters, for a readership interested in mythology and hydraulics. The two woodcuts show fantastical dragon-like war machines on wheels, drawn in plain black line with hatched shading, with simple ground lines and little background. A designer might take their stiff, mechanical monster forms and the hatched engraving texture for vintage illustration or sci-fi motifs.
