“TERENCE SMITH: The idea for the tribute was born in the initial hours after the attacks. Several different artists and architects, including Bonevardi and his partner, John Bennett, had similar visions purposes in mind.
GUSTAVO BONEVARDI: At that time on the 13th, the first week— the 12th, the 13th, the 14th— we still thought that hundreds of people were going to be rescued, were going to be pulled out from the rubble. What we really wanted to do— we wanted to do a sign, a symbol to inspire the rescue workers. We wanted to... not recreate the buildings, we wanted to somehow heal the Manhattan skyline. We wanted to help the city with these lights to get it through its darkest time.
PAUL MYODA, Artist: Within the space of a very few minutes, the idea sort of revealed itself to us, that this sort of ungodly plume of smoke, this illuminated smoke cloud, which every New Yorker will remember forever... we thought about sort of reconfiguring the chaotic smoke cloud— we wanted to reconfigure it into the orderly image that was in our mind's eye.
JULIAN LAVERDIERE, Artist: And it was very much in the spirit of the candlelight vigils that were held immediately within the following nights— tens of thousands of candles lit by people in all walks of life, nobody knowing one another, but joining together in mutual grief. And it dawned on us that that's what we should build: Some sort of structure that could generate that same sensation.
GUSTAVO BONEVARDI: My only explanation in a way is after having stared at those towers for so many hours that day, you'd close your eyes and it's like an afterimage. You would see the towers as a negative on your retina. And I think it's this vision that so many people in the city had. »
