Kumfanekiso kaJosefu uJoseph Wright, obhalwe ngo-1768, kuvavanyo lwalubonakaliswa, olubanjelwe ngentaka kwimpompo yomoya. Lo mfanekiso okwangoku ubekwe kwigalari yesizwe eLondon. Umculi wayelilungu ngqo la mava, ke umfanekiso ulixabiso lembali.
Inzululwazi iboniswe kwi-canvas, ithathe indawo yokuvavanywa kwempompo yomoya yeRobert Boyle - I-Anglo-Irish Chemist kunye neFizish. Esi sixhobo senzelwe ngokuthe ngcembe umoya otyhalela umoya kwi-vacuum.
Ngenkulungwane ye-17, izazinzulu zazinomdla kwindlela izinto ezingenankathalo ziya kuziphathe. Emva kokufunda imeko yezilwanyana ezingaphili, baqala ukubeka izinto eziphilayo: izinambuzane, iigundane, iintaka.
Iimpompo zomoya, ngaphandle kweendleko ezibizayo, zisasazeke kwiisaziso zesayensi kwaye azikho kuphela. Iqela elithile labantu lavela, lafumana imiboniso enjalo izilwanyana kwindawo engenamntu yenani elikhulu labantu.
Amatikiti athengiswa kwiminyhadala, iintetho zaboniswa kwiiklabhu ezahlukeneyo kunye neeholo zedolophu, okanye umboniso wawuqhutywa kwiindawo zabucala kwisangqa sangasese. "Mboniselo" onjalo kwaye uye kumculi owawukhuphela emfanekisweni.
Lo mfanekiso ubonakalisa i-parrot emhlophe nge-hookholcom entloko, efana ne-cacatoo. Uvavanyo luphantse lugqityiwe, kwaye intaka ilele emazantsi etanki edinwe, kodwa iphila.
Mhlawumbi intaka yantlandlolo ithathe inxaxheba kwasekuqaleni. I-parrot ngamaxesha ahlukeneyo yayingeyongozi. Umvavanyi ubambe isandla kwivalve kwaye ujonge abaphulaphuli. Ukulungele ukubuyisela umoya emoyeni, kodwa akukho namnye kwabo bakhoyo.
Emfanekisweni, enye intombazana icaphukisa kakhulu, kwaye kangangokuba utata wakhe uyayithuthuzela, eqinisekisa ukuba yonke into ihamba kakuhle intaka. Kunye naye, kuphela ngabantwana abanemfesane ngentaka yokuvavanya. Amadoda abukele uvavanyo ngenzala, elinde ihlazo, kwaye izithandwa zingena kwelinye icala.
Omnye wezazinzulu ezaziwayo eziqhuba iimvavanyo zoluntu ngempompo yayinguJames Fierguson, umzobo we-astronomer kunye nomfanekiso oqhelekileyo wokupeyinta. Waqinisekisa ukuba zizidalwa eziphilisayo awayehlala kuzo.
Uninzi lweemvavanyo zabekwa emoyeni ezaliswe ngumoya, kwaye abaphulaphuli baqwalaselwa ukuba bavuthele ibubble. Yintoni enokuba ngcono, kuba ayinguye wonke umntu okwazi ukuzolisa indlela "ashiya ngayo".
