Dionysios Philosophos (Διονύσιος ο Φιλόσοφος, Dionysios the Philosopher) or Skylosophos (Διονύσιος ο Σκυλόσοφος; c. 1541–1611), "the Dog-Philosopher" or "Dogwise" ("skylosophist"), as called by his rivals, was a Greek bishop, who led two farmer revolts against the Ottoman Empire, in Thessaly (1600) and Ioannina (1611), with Spanish aid. He is considered one of the most important bishops of the Greek Orthodox Church who acted conspiratorially and revolutionary against the Ottomans during the Ottoman rule in Greece. Dionysius was born in 1541 in Aydonat in the Rumelia Eyalet of the Ottoman Empire (modern Paramythia, Thesprotia, Greece). He was of Greek descent from the region of Epirus. At a very young age, Dionysius became a monk at Dichouni in the Ioannina region. At age 15, he went to Padua where he studied medicine, philosophy, philology, logic, astronomy, and poetry. He took the name "Philosophos" (philosopher). In 1582, he lived in Constantinople and in 1592 he was elected metropolitan bishop of Larissa and Trikala. Due to his astrology, fortune-telling activities and contacts with demons he was deposed by the Patriarchate of Constantinople. Thessaly rebellion (1600) Dionysius led a farmer revolt in 1600 in the region of Agrafa. He was demoted from the rank of metropolitan bishop of Larissa for his public speeches inciting rebellion and for his related fundraising activities. He subsequently left for the Republic of Venice where he raised enough funds to pay for a peasant army and tried to get contact with the Pope. After returning to Greece, he made his headquarters in the Monastery of St. Demetrius in Dichouni ( Διχούνι) of Thesprotia. As a monk, he toured the surrounding villages, raising an army of about 700 men. Armed with simple weapons, his army succeeded in several surprise attacks against the Ottoman garrisons of the area. Encouraged by these successes, he led his army into Ioannina on 11 September 1611. The inhabitants of the city were so surprised by the sight of the armed men and the fires that they turned against each other in confusion, unaware of the purpose of the fighting.
