Dans son journal, figure aussi la restitution en couleurs de l’homme ailé représentant probablement une divinité importante des Achéménides, qui apparaît sur beaucoup des bas-reliefs de Persépolis (voir la figure 1). Lorsqu’il mit au jour le palais de Pasargades, Herzfeld découvrit aussi des restes de moulures comportant des peintures ornementales. Elles ornaient les colonnes et les murs de brique d’argile du palais, dont seules les fondations de pierre sont encore visibles aujourd’hui. Les restes de pigments et de dorures, les trous d’ancrage d’ornements de métal, ainsi que les fragments de briques émaillées et de peintures murales suggèrent que les palais achéménides étaient couverts de couleurs, qui nous paraîtraient aujourd’hui bien trop vives.

Ocre rouge Dans les microcreux de cette surface grossièrement polie se trouvaient des traces d’un gris blanchâtre, probablement un reste du premier habillage de couleur de la statue. La comparaison avec d’autres statues égyptiennes nous fit conclure qu’au moins les yeux, les ornements et les bijoux avaient été recouverts d’une couche de peinture. Avec un microscope électronique à balayage,Andreas Burmester, Christoph Krekel et Andrea Kaser, de l’Institut Doerner à Munich, ont examiné de minuscules échantillons de la roche de sur- face en appliquant le processus dit de l’analyse dispersive en énergie, et ont ainsi décelé la présence de calcite.

L’étude des décors muraux peints retrouvés par les fouilles archéologiques dans l’ensemble du monde méditerranéen met en évidence l’élargissement progressif de l’aire d’utilisation du bleu égyptien.
