Meaning of "Homo Rebus"

Question

I read a literary text originally written in Portuguese, The monologue of hands by Giuseppe Ghiaroni. I can't understand this passage in Latin :

O autor do "Homo Rebus" lembra que a mão foi o primeiro prato para o alimento e o primeiro copo para a bebida.

The author of "Homo Rebus" reminds us that the hand was the first plate for food and the first glass for beverage. [my translation]

First I thought Homo Rebus was the title of a Latin literary work. But I couldn't find any work with this title.

Is there any famous passage in Latin language with the expression homo rebus that refers to the hand ?

Answer 1

The auctor intellectualis of Homo Rebus is Milivoj Bijelić, a Croatian artist born in 1951.

It is an image, not a literary work.

I found a reference on this website: https://nmmu.hr/en/2022/07/20/milivoj-bijelic-denkbild-strikte-observanz-2002-2/

Bijelić establishes his own sign Homo rebus that he shapes into an enigmatic pictogram, a paraphrase of Da Vinci’s man with outstretched limbs which he modulates in paintings, painting-objects and installations (45th Venice Biennale, 1993). This sign is the measure of all things, and transformed into an artistic matrix it is an image of the figure and the figure of an image, a code and a sign of the human figure in general.

If you open the site, the image shows up on the right. A little further down we find:

He participated in the Biennial exhibitions in Saõ Paolo [sic] in 1982 [...]

This makes it plausible that Giuseppe Ghiaroni (1919-2008), being Brazilian, has seen Bijelić' work. It does not explain the link between the image and the poem, but that might be something for another forum.
