The Pneumatics of Hero of Alexandria

Of drawing water by way of a bent tube at page 9.
Of the Spiritual tube in the middle of another tube in the upper mouth. 11
Of the flow always equal, through the bent tube. 13
Of the flow through the bent pipe, part equal, and part unequal. 13
Of drawing water out of large pipes. 15
Of the hollow copper ball. 15
That one can fill the concave ball with hot water, and cold, one separated from the
other, and send them out, when one, when the other: and both together. 16
Of the vessel called Prochita, which was used in ancient times in sacred Ministries. 17
Of the Sphere, or concave ball, which by itself expresses water upward. 18
Of the box referring to a mechanical casing or container. 19
To make animals sacrifice as many as we wish by the force of a lit fire. 20
Of Vessels, which if they are not full do not pour: but when full all the moisture
that is inside runs out. 21
Of concordant Vessels. 22
Of vessels into which, by pouring water, a sound is created, or hissing. 23
Of the diversity of the voices of various birds. 24
With the same reason, Trumpets are made to sound. 25
In opening the doors of Temples, in this way it is done, that one or more trumpets
sound, at page 25.
Vessel, into which wine and water are infused, separated from one another, one can
have at our pleasure, when pure wine, when pure water. 26
Of the cup placed on a base, if wine of which it is full is drawn from it, it will
immediately return by itself to fill up. 27
That the proposed cup (although a great quantity of wine or water is drawn) will
always remain full. 28
Vessel in which, having thrown a coin of five drachmae, water comes out and
sprinkles the one who places the coin in the Vessel. 29
Having placed in a vessel various sorts of white wine, red, of more flavors, and
water, to make them exit at our pleasure through a single channel. 30
The two Vessels, which placed on one same base, one of which full of wine, and
the other empty, and that as much water as will be placed in the empty one, so
much wine will come out of the other, are manufactured in this way. 31
To manufacture a pipe that flows as much water and wine as we wish. 32
If there is water in a Vessel, and in it a channel in which there is a key, and in
said water an animal swims: to make it so that as much water as is drawn from
the vessel, the animal sprays as much wine from its mouth. 33
But if we wished to see as much wine come out as water is placed in a vessel, thus. 34
Manner with which water is expressed in fires. 34
In places where one will have water running through a channel, to manufacture an
Animal, or dra-

-gon, or of whatever other material one desires, that continually cries: but if I
bring a basin of water, it drinks it without noise, and having drunk it, it returns
to crying again. 36
How in another way, by turning a key through the work of the effusion of water,
one makes the same Animal drink at our pleasure. 37
How, without flow of water, by turning a key, one makes the aforementioned
Animal drink. 38
At the doors of the sacred Temples of the Egyptians, wheels are made to turn,
which are turned by those entering the Temple, and after the doors are turned, in
the turning of those wheels they spray water and sprinkle those entering, and in
this way they are manufactured. 38
Through the mouth of a Vessel one can place in it more sorts of wine, and through
one same channel draw each of them at the pleasure of the one who wishes for
whatever he wants, indeed if many sorts of wine are placed there, everyone will
be able to have his own, and especially as much as is placed inside of each. 39
To manufacture a lamp that consumes itself. 41
If in a Vessel that has a channel open near the bottom we place water, to make
at our pleasure water exit through that channel at the beginning, sometimes in
the middle, and sometimes when the whole vessel is full; or that in general, as
soon as the Vessel is full, the water will run out. 41
To manufacture a Vessel into which, by pouring fluid, it will receive it; not
pouring more water into it, it will not receive more. 42
On a base one can place a Satyr, who holds in his hands a Wine-skin, under which
there is a Ring vessel or basin which, if it is full of water, it will fall through the Wine-skin into the said
Ring; nor will it ever overflow at the edges of the Vessel, until all the water
has been evacuated through the Wine-skin, and the way to manufacture it will
be this. 43
To manufacture an Altar upon which, a fire being lit, the doors of a Temple open
immediately, and the fire being extinguished, they immediately return to close. 44
Also, a fire being lit upon an altar, the proposed doors are made to open. 46
Having filled a Vessel with wine, which has three channels, to make it so that
through the middle one wine exits, and when water is added to that Vessel, that
the flow of wine stops, but water exits through the other two channels, and that
water being stopped, the wine returns to exit through the middle channel, and
this as many times as we wish. 47
If upon a given base one makes a patch of trees, and in it a Dragon is entangled,
and opposite it a Hercules in the act of shooting, if anyone removes a pomme apple/fruit
from the base, to make Hercules shoot at the Dragon, and the Dragon send forth
a Hiss in this. 48
To manufacture a Vessel, which whenever it is poured will give an equal measure
of the fluid contained by it, which is precisely called a vessel of just measure. 49
With breath, to express water out of Vessels in this way. 50
To form various voices of various birds at more distances. 51
In another way still, at different distances, different songs of various birds are made. 52
To make empty and light Balls hop in this way. 53
And transparent Spheres, which have in themselves both air and water, and in the
middle a ball, like the earth in the middle of the World, are made in this way. 53
