Constantine Simonides (1820–1890), palaeographer, dealer of icons, man with extensive learning, knowledge of manuscripts, miraculous calligraphy. He surpassed his contemporaries in literary ability. According to opinion of paleographers, he was the most versatile forger of the nineteenth century.
He was born on the small Greek island of Symi, on the coast of the Aegean Sea in 1820 (or in 1824), and died in Egypt of leprosy.
Simonides lived in the monasteries on Mount Athos between 1839 and 1841 and again in 1852, during which time he acquired some of the biblical manuscripts that he later sold. He produced a lot of manuscripts ascribed to Hellenistic and early Byzantine periods. He allegedly forged a number of documents and manuscripts and claimed they were the originals of the Gospel of Mark, as well as original manuscripts of poems of Homer. He sold some of these manuscripts to the King of Greece. Greek scholars exposed what some claimed to be forgeries quickly and he left Greece and traveled from country to country with his manuscripts. He visited England between 1853 and 1855 and other European countries, and his literary activity was extraordinary. Some of his works were published in Moscow, Odessa, in England, and in Germany. He also wrote many other works which were never published.
From 1843 until 1856 all over Europe he offered for sale manuscripts purporting to be of ancient origin. He created "a considerable sensation by producing quantities of Greek manuscripts professing to be of fabulous antiquity – such as a Homer in an almost prehistoric style of writing, a lost Egyptian historian, a copy of St. Matthew's Gospel on papyrus, written fifteen years after the Ascension (!), and other portions of the New Testament dating from the first century."
In 1854 and 1855 Simonides tried unsuccessfully to sell some manuscripts for the British Museum and the Bodleian Library. Thomas Phillips was a less critical purchaser and bought for the Phillips Library at Cheltenham some manuscripts. In 1855 he visited Berlin and Leipzig. He informed Wilhelm Dindorf that he owned a palimpsest of Uranius.
