This 'calligramme' comes from a Persian copy of an astrological work. The copy is dated to 1847/8 AD. The text gives the correspondence between letters and celestial bodies.
(The image was redrawn from Salah Stétié, Fridaws, Essai sur les jardins et les contre-jardins de l'Islam, Paris, Le Calligraphe, 1984, p. 5.)
In countries of Islamic culture a cryptographic notation was used, based on the «arboriform» alphabet (al-khatt al-mushadjdjar), which symbols are indeed in the shape of trees.
It served the confidentiality needs of the army and particulars, as well as being a writing for mystical and alchemical secrets.
One of its many variants is caled 'Dioscoride's'. We choose the fourth letter of the alphabet - the lettre dâl or /d/ - to remplace in the current useages our grand logo by a simpler sign.
(The «arboriform» alphabet is to be found in many mss - here is the reference to one of them: Ms de 1849/50, Tarih 812, fol. 82r°-v°, Millet Library, Istanbul ; reproduced in Abdülkadir Dedeoglu, Mizânü'l hatt, Istanbul, Osmanli Yayinevi, 1986, p. 194.)
The logo of the Kabikadj programm was designed by Robinson Deschamps, while a graphical Arts student at the «Scriptorium» of Toulouse, France.
