Theory time...
The di Giorgio (bottom left) led me to wonder which places in Italy or Southern Germany has Obelisks or lighthouses. Turns out Naples does and his sketch was for the fortifications of Naples. The painting above is a 1498 of the same. Also visible in the top left of the painting is the Fanale which was cylindrical and id say a decent match for the object at the top of the Voynich illustration
