Evidence

"Among those ‘properties’ learned by Zacuto in Poland, one can find advice... on preparing ink visible only under water..."

Remarks

This ink is part of a category of recipes collected by Moses Zacuto in Poland referred to as 'properties' (segulot) (p. 276-277). Unlike amulets and adjurations that rely on divine names, these properties manipulate the inherent qualities of matter. The preparation is situated within a worldview where elements of the environment are connected through visible and invisible bonds (p. 277).
