The Typos of Emperor Constans II was an Imperial edict issued by him in September of 647 or 648 and meant to supersede Heraclius' Ecthesis. "Typos" is short for "Typos tes pisteos" or "Pattern of the Faith."
It was probably the work of Patriarch Paul of Constantinople (r. 641-653), commissioned by the emperor. Attempting to secure peace during the Monothelitism controversy, it forbade the teaching of either the heretical Monothelitism or the Orthodox Dyothelitism, requiring that teaching should be limited only to that which had been decreed at the first five Ecumenical Councils.
When Pope St. Martin of Rome refused to accept the Typos, he was deposed and exiled to Crimea in 655. St. Maximus the Confessor earned exile to Thrace in 653 for his own refusal to sign.
The text of the Typos is preserved in the Acta of the Lateran Council of 649.
