3. the tendency of heavy things to descend and of light things to rise

air = vital spirit that joins things together, resounding spirit if the world instrument

Paraceksian theory of aerial niter
(an active principle) aerial version of earthly gunpowder - responsible for life, combustion, thunder, lightning, (some) illnesses
--> connecting the activity of air + life + weather phenomena

wind: (***in its irreducible qualitative variety***) expression of cosmic spirit + محرک باعث a motive force to be accurately estimated

منجنیق ~= geometry هندسه *pneumatic engineering* : distinction between moving and moved components ==evoke==> motive forces
elaborated pneumatic machines
mechanical clocks
tension of strings

*wind ==> celestial influences*
(Cardano regarded) expansion and contraction of air as symmetrical phenomena, both consisting a source of motive forces
-in the universe the element air had the function of receiving and conveying fiery celestial influences on earth providing health and wellbeing fir living creatures

Telesion (1509-1588)
soul and spirit identified with each other as a very subtle material substance pervading all bodies and making them capable of sensing and reacting to rach other with pleasure or pain
*(man’s) immortal soul did not play any role in determining natural phenomena*

innate heat of living bodies

wind: humid vapours flowing through the air
thinness of wind vapours


16th century
expiration and inspiration of the lungs
Holy Spirit is expressed in the nature of winds
interest in wind and weather was kindled by reports reaching Europe from the East and West Indies about hitherto unknown meteorological phenomena عجایب


orderly majesty of God ==> encyclopedism about the universe + an analogue of a memory system

Jean Bodin
firm believer in and opponent of demonic magic
theater of the whole nature universe naturae theatrum
reason of wind (ratio ventorum):
•sun
•impulse (impulsus) of the angels or demons


sphere of sacrobosco
De sphaera mundi
(On the Sphere of the World, pre-Copernican astronomy)


...our sublunar world

gunpowder theory of thunder ⛈
compact earthly matter from underground whose expansion with expansion so fast that it moves large masses of air, like “salniter in fire or gunpowder which has caught fire”


visualization
making air visible
inverted glass experiment
linking thermal expansion & contraction of pure air to wind formation (Cardano)

(under the influence of) celestial fire ==> air (could become alive and active) acquiring motive force

on the transmutations of air

(typical of 16th century) steering the religious significance of the study of nature
spirit: a cosmic subtle substance, both recipient + vehicle of celestial influences ==allow==> elements to transmute into each other (+ meteorological phenomena)
(Drebbel’s favourite cosmic spirit:) fire = clearest of all elements ad top of the hierarchical order of elements (fire, air, water, earth), clarifying the other elements [such as Siavash]

(for Della Porta:) meteorological phenomena = transmutations of the air (in literal sense)
air becoming thinner or thicker ==rise==> winds, thunder, clouds, rain, snow, linking heaven + earth + bringing life to all animated creatures

(Della Porta conceived of) wind in vitalistic terms
...winds rising up from the mouth of the retort (boiling water)
how heat endowed air with motive force


(Drebbel presenting to the public) perpetuum mobile : expansion and contraction of air (which he claimed) demonstrated the force behind all movement and life

weatherglass (+ aeolipila) --demonstrated--> ****highly nontrivial natural phenomena**** (transformation of energy from heat into mechanical motion)

(ajayeb’s) theory about the origins of the wind

Galileo --> earth's rotation ==> (<--evidence--) wind
Bacon --> exhalations together with air [rarefaction and expansion of air / exhalation drawn up by sun] ==> wind
Fludd (meteorological cosmica) --> wind: principal meteorological phenomenon (princeps meteororum) and closest to God
“wind is an aerial spirit, of middle consistence, inspired or animated by the breath of Iehova, which he extracts from his treasure-case according to his will, to effect either a punishment or a benediction”
•angels: efficient cause of winds (in borg macro- and microcosmos)
•(changes in the air --corresponded-->) temperament of living creatures ==> wind
•pulse of the heart caused by the spirit of life
•thermal expansion
•vaporization (+ contraction) of air
•pneumatics


“wind = thermal expansion & contraction of air” --> a vitalistic-alchemical Rosicrucian conception of meteorology and cosmology =/= Descartes’ mechanical-corpuscular view of nature -->{wind <== vapours drawn up from earth and water by solar heat (vapours expanded when heated and when they encountered the opposition of other vapours clouds or mountains they ended up escaping in the one free direction)
•vapour: (made out of) small corpuscles together with even smaller particles filling the gaps between the corpuscles

Froidmont --> wind: (made of) dry and hot exhalations =/= animated (as the stoics dream)
{winds flow towards Earth because of their gravity, like streams and rivers in their beds} gravity ==> wind =/= (direct expression of) celestial power and caused by God’s angels


scorched by rays and reflexes of the sun
denser


Torricelli conceptualized the motion of the hot and cold air masses by thinking them as separated by the walls of a building and in this way he ignored the air’s life-like tendency to expand when heated. instead he reasoned in terms of change of weight applying Archimedes principle


علم کلام
*reflections grounded on literary descriptions of ancient artefacts*
+ based on actual devices
--> wind = source of a potentially infinite quantity of motive force, the multiform expression of a single cosmic principle animating air

inverted glass experiment : a ***demonstration ~= simulacrum*** (of celestial motive forces) [~=? a fable]
#a demon working on demonstrations

mechanistic explanations ==> mechanical conceptualization:
•astronomical clocks
•clockwork automata
•computing machines
•optical tricks

--Borrelli--> weatherglass only became interesting when considered as a means of quantifying phenomena

*artefacts and artificial processes that lent themselves to conceptualization in vitalistic terms:
•alchemical experiments
•magnetic compass
•pneumatic engines
•speculate on wind
•falling bodies
•pendulum


(Halley’s) wind: successions of strokes indicating the direction in which a ship would travel under the influence of the wind blowing (at the specific point of the sea...) -~-~-> direction of a virtual invisible motive force

(?) people rely on singular ontology and multiple epistemologies

interpretation =? appropriation of other's existential labor (~/= culture)

Alberti's pot: instantiations of a concept of a world that is chronically unstable
(cranial modification, tattooing, treatment of the dead --manage-->) the inherent instability of bodies
•one's perspective is intimately connected to the body one is
