Origin of the phrase "useful, usable, and delightful" or variant?

I feel like it was from an architect of antiquity but preliminary searches haven’t turned up anything. Trying to avoid a deep dive through long discussions about the distinctions between art/artisan/architect/design/engineering etc.

The answer you seek is Marcus Vitruvius.
In the book De architecture he called out 3 properties: firmitas, utilitas, venustas.
These have generally been translated as solid, useful, and beautiful … or quality, commodity, connection.

Awesome. Thanks!

Also, I almost spoke the question aloud assuming you would hear.
