From "The Coronavirus Crisis Reveals New York at Its Best and Worst/In a time of containment, the city searches for a way forward" by Adam Gopnik (in The New Yorker).
Here's "The Plague" by Albert Camus, in case you don't already have it and you want to read/reread it. I just put it in my Kindle (though I have read it twice, quite a while back, including that time in high school French class).
And here's the Giacometti sculpture I'm 99% sure Gopnik had in mind:

It's "Piazza" (a familiar sight at the Guggenheim in NYC). And here's sculptor's explanation:
"In the street people astound and interest me more than any sculpture or painting. Every second the people stream together and go apart, then they approach each other to get closer to one another. They unceasingly form and re-form living compositions in unbelievable complexity.... It’s the totality of this life that I want to reproduce in everything I do...."So Giacometti did not think his figures were — as Gopnik put it — "walking but never intersecting." Giacometti saw the figures streaming together, then going apart, then approaching again. The artist was not — as Gopnik saw it — "see[ing] what cities aren’t." That is, the writer was seeing what the sculptor was not.
Giacometti was seeing what cities are — in times of plague and normal times — a living, moving, continual coming together and moving apart. We're in an apart phase, but we are together in our hearts, and we are keeping the city — the civilization — alive.
