to the original left of Gioconda, at the center copy of Sandro Ferrucci and to the right copy of the Prado

Continue my studio / copy of the hereafter documented other mistakes that Leonardo did not expect because of the decorative geometries and in the other photo document the scar of the copy maker of the Prado.

mistake in the dress of Gioconda

in the picture above error in the original of the Gioconda where the decoration sequence at one point has 4 octagons between a cross-decoration and the other instead of every 3 octagons com indicates instead the frequency.

copy detail of the Prado

above from the copy of the Prado we can notice how the decoration of the gown is reproduced more coarse than the original, where the weaving of the octagons above is clearly smaller and realized of larger size, the same is true for the decoration under the weave of octagons interspersed with 5 crosses rather than 7 as in the original.

The design of the copy is exactly the same as the original (only the right hand 8/9 mm higher than the original one) because the original cardboard transferred to dust will most likely have been used on the copy as well.
