Good morning on this murky Monday.

Long before Christopher Columbus sailed the ocean blue, indigenous New Yorkers lived on an island they called Manahahtaan.

And thousands of Native Americans are still living in the New York area.

There are Aztecs and Mayans in Sunset Park and Mohawks in Bay Ridge. There are Shinnecock, Unkechaug and Ramapough in our suburbs.

So today, New Yorkers are celebrating both Indigenous Peoples Day and Columbus Day.

But in the wake of the violence this summer in Charlottesville, Va., sparked by a white supremacist rally protesting the removal of a Confederate general’s statue, New York City is deep in its own debate about who we should (and should not) memorialize in 2017, and what to do about statues seen, Mayor Bill de Blasio said, as “oppressive and inconsistent with the values of New York City.”

And Columbus, long the honoree of this October holiday and the namesake for one of our city’s most famous thoroughfares, is at the center of that debate.
