Nebuly lines occur in early heraldry, but they are uncommon. [...] German heraldry used the term 'gewolkt' from 'die Wolke' also meaning cloud. Form and definition were well established before the 15th c.

Register or Login to view.Even ignoring its probable sourcing from the Oresme diagram, the figure of f69v3 almost certainly depicts the same concept of the cosmos: with "land" and the "waters below" (seas) at the center, surrounded by the stars, separated from the "waters above" by the vault of the "sky". The wavy line of f68v3 should have been the latter, and therefore should have been a "wolkenband" as in the Oresme diagram -- not a nebuly line.
But actually it is neither: it has a 3D effect (unlike the "nebuly line" of heraldry) but not the fine frills along the edge (unlike the standard "wolkenband").
