Giovannino de Grassi's workshop predates the VM but operated well within the VM timeframe under his son. While not especially close to the VM these might have been precursors. Grassi's image studies were famous. Interestigly this was pretty much the pinnacle of medieval art, most later artworks were much cruder.

By the way, according to Wikipedia, some images of the Tacuinium sanitatis are derived from Codex Palatinus 586 (Circa instans) and [i]Codex Casanatensis 459.[/i]
