Three-section orbs

[MarcoP]

PS: the page linked below gives the following description (emphasis mine):

In 1224 the religious house of San Quirico near Antrodoco within the diocese of Rieti was engaged with the bishop of Penne in a struggle about jurisdiction over a group of churches locally within the diocese of Penne.[15] Among these was the twelfth-century collegiate church of Santa Maria di Ronzano near Castel Castagna, which with many of its twelfth-century frescoes still survives. One of these frescoes, from the Old Testament cycle, the creation of the world (plate 8), offers a last opportunity for warning the reader about the complexity of memory and time, the inventiveness to which both of these concepts, both continually important to this book, are susceptible. The God who creates the world of the fresco is Christ, the Redeemer, with the wounds from the nails clearly apparent in His hands and feet. The world He creates is a disc within a circling firmament decorated with heavenly bodies. The disc itself is cut as if by the letter X into four parts, of which the top three represent aspects of earthly nature. In the fourth a man brandishing an axe, as if to clear for planting, stands behind a pair of oxen pulling a plow: that is, a representation of the labor to which humankind was driven after the Fall.

So the image is not relevant for the topic.
