Iconostasis: a high liturgical barrier, present since the 11th century in the Eastern Greek churches and only rarely in the West, used as a dividing element to separate the choir from the nave, and as a surface on which to expose a variable number of icons to the faithful.


Illuminated manuscripts: handwritten, books with parchment sheets in use before the spread of printing on paper (15th century). These codices were often true works of art due to their illuminations, i.e. precious, miniature decorations.

Incunabula: the first books printed with movable type technology between the mid-15th century and the year 1500.  The name derives from the word incunabulum (the plural becomes incunabula), meaning “in or from the crib”.

Inlay: decorative technique that involves carving a surface (like wood, metal, stone, etc.) creating grooves into which precisely shaped elements are inserted.
