Subsequently, F. Pavia pursued further research, shifting his focus to a set of engravings on the rocky surface, which he interpreted as a multitude of “stars” arranged in “constellations.” The presence of both the “bowls” and the “constellations” on the same rock is believed to bestow significant archeoastronomical value upon it.
In the early twentieth century, Ludwig Schwennhagen, originally from Austria, conducted extensive research on Brazilian history. His studies revealed striking resemblances between the symbols present on the Ingá Stone and the iconography associated not only with the Phoenicians but also with the demotic writings, primarily used for business and literary documents, of ancient Egypt. Additionally, other groups of researchers discovered a remarkable similarity between the carvings found on the Ingá Stone and the indigenous artwork found on Easter Island.
