In 1968, Vaziri moved to the Cité des Arts in Paris, thanks to a grant, and he continued developing his work with aluminium and ondulated pieces of wood. That same year, his works were presented at Royan International Festival and exhibited at the national TV headquarters.
Once he returned to Iran that same year, he started making his articulated sculptures – open and interactive artworks which encouraged the viewer’s participation.
“These sculptures possess elongated, and serrated wooden parts attached to their middle bases through joints which could be manipulated and moved. In Vaziri’s own words, ‘they would open and close just like human joints’. According to the artist, the idea of these moving parts occurred while making and cutting pieces for the fixed sculptures. These earlier, immobile sculptures were actually devised from intersecting a few shaped, colorful flat plates, like fragments of a paintings.” (Darabi, 2021)
During the 1970s, these sculptures would in turn inspire a series of paintings entitled Fear and Flight that marked a return to the well-defined shapes (both pointed and rounded) of his tri-dimensional works and developed them further. Alberto Moravia and Pierre Restany are amongst the eminent art critics that wrote about his work.
A constant and essential theme in his work–whether in painting or sculpture–was that of space, which led to results much appreciated by critics (Argan, Moravia, Bevilacqua, Menna, Pensabene) and to a recognition awarded by the City of Rome (1958), Prime Minister Segni (International Art Competition, Ravenna 1959) and the Senate Gold Medal (Sassoferrato 1962).
His works have been shown in numerous solo exhibitions in Italy (Rome, Milan, Florence), Germany (Dusseldorf, Munich), and Iran, at the Venice Biennial (1956, 1958, 1960, 1962), at the Tehran Biennial (1960, 1962), at the Rome Quadriennale (1960), at the Sao Paulo Biennial in Brazil (1963), at the Museum of Modern Art, New York (1964) and at the Shiraz Art Festival, Iran (1969).
In 1985 Vaziri decided to return to Rome, the beloved city of his artistic training and development, with his wife and two children.
