Asking for help with a fake Hebrew text

[jmacdonald]

Greetings

Could anyone kindly help me with the following?

The image below is a detail of a 15th century painting.

Its "text" is usually interpreted by scholars as fake Hebrew, at it most probably is. (I do not know Hebrew.)

Nevertheless, and here's my question, though being fake Hebrew, to what variant of written Hebrew could it be similar to? That is, what type of Hebrew was the artist author of the painting trying to imitate?

Many thanks in advance for any help.

Best regards,

João

To be honest, I can’t make enough form to even begin to have an opinion. What is the painting, who is the artist.

In a mirror view there seem to be some numbers (1,4,5,6 and 9)
