Courtesans through out the medieval period in the Middle east had very elaborate hennaes to enhance their beauty and sensuality.  Sa'di,  Persia's greatest poet wrote in the 13th century in the city of Shiraz.  He wrote passionately of loving courtesans,  the beauty of his lovers, and how one should never scorn love.  In Shiraz, a beautiful woman had  wide black eyebrows, hennaed hands, scented with perfumes, and was graceful and seductive.  Sa'di man reached out to the divine by adoring them with all his being.  Sa'di often argued that a courtesan or prostitute's beauty and love is as worthy a path to spiritual perfection as prayer and self denial.
