Micrography

Micrography (from Greek, literally small-writing – "Μικρογραφία"), also called microcalligraphy, is a Jewish form of calligrams developed in the 9th century, with parallels in Christianity and Islam,^[1] utilizing minute Hebrew letters to form representational, geometric and abstract designs. Colored micrography is especially distinctive because these rare artworks are customarily rendered in black and white.
