Here is the original work[1]. And not only the hierarchy is never mentioned. Also, the whole publication is just an essay that lacks any kind or form of research.

He never represented it as a pyramid, but he clearly described it as a hierarchy.

Yes, I mispoke and used hierarchy interchangeably with pyramid.

The whole essay talks about various hierarchies, literally the defining theme is hierarchy of motivation

> And not only the hierarchy is never mentioned

That's absurd. The entire essay describes the hierarchy.

Thank you for the link, but I'm curious why you didn't read it yourself before you made your assertion?

"But what happens to man's desires when there is plenty of bread and when his belly is chronically filled?

At once other (and 'higher') needs emerge and these, rather than physiological hungers, dominate the organism. And when these in turn are satisfied, again new (and still 'higher') needs emerge and so on. This is what we mean by saying that the basic human needs are organized into a hierarchy of relative prepotency. "
