The Manuscript Codex * The Binding
ENVELOPE FLAP

The pentagonal piece of board and covering material which in a typical Islamic binding extends from the fore-edge flap with a flexible joint. Usually the envelope flap was inserted under the front cover or slid between the leaves of the manuscript. In rare cases it may lie over the front board. This latter arrangement is obligatory if a fastening strap extends from the point of the flap, which was used to wrap around and secure the book.
