Nel 1913 Malevic espose un quadrato nero, dipinto su tela bianca. Veniva mostrata una forma opposta a tutto ciò che si intendeva per dipinto, pittura, arte. L’autore voleva così zerificare tutte le forme, ogni pittura. Ma per noi questo zero fu il punto di svolta. Se abbiamo una serie che parte dall’infinito…. 6 5 4 3 2 1 0, si giunge allo 0, e quindi comincia la linea ascendente 0 123456… il quadrato costituisce il fondamento della nuova costruzione spaziale della realtà. La sollecitazione occorrente provenne dal suprematismo. In un tempo in cui la pittura era appesantita da quanto c’è al mondo di estraneo a lei, si doveva cominciare con far pulizia. Il suprematismo si mise in cammino per liberare la pittura dalle stratificazioni che erano cresciute sulla sua essenza, cioè da quelle dell’azione immediata del colore sull’occhio. Ma il colore viene comunque chiuso in una superficie. Così nasce la forma. Questa deve essere univoca. Univoca, cioè riconoscibile subito da tutti, è la forma geometrica.

What to do if you see whales and dolphins
Watching whales and dolphins in their natural environment is an exciting and rewarding experience. It is important to remember that our actions can disturb these wonderful animals. This is why the Australian Government has worked with state and territory governments, non-government organisations and the whale watching industry to develop the Australian National Guidelines for Whale and Dolphin Watching.
