Watermarks - Islamic manuscripts

Illuminated Qur’an, from South-East Asia, not
dated, but 19th century, assumed so because of
provenance history as it was once owned by the
Dutch orientalist Taco Roorda (d. 1874).
Naskh script for text. Elongated script used for
the headings. Beginning of sura 18 (al-Kahf),
whereby the illumination serves to indicate that
the reader is halfway the text. Right half of an
illuminated double page.
