Papal Bulla Innocent IV 1243 - 1254
PAS: A Medieval lead Papal bulla of Pope Innocent IV, whose papacy lasted from 1243 to 1254 AD. The obverse depicts the faces of St Peter and St Paul below the inscription SPASPE (SPA = Sanctus Paulus, SPE = Sanctus Petrus), all of which are surrounded by a beaded border, flanking the outside edge of the bulla. St. Paul is seen on the left looking right, with a long pointed beard, and St. Peter is on the right facing left, with a rounded face and beard and hair formed from pellets. Each is within a C or backwards-C beaded border, joined to the main. The reverse bears the legend INNO/CENTIVS/.PP.IIII. , within a beaded border. There is an omega above the 'PP', which is an abbreviation of pastor pastorum - meaning shepherd of the shepherds. The surface of the bulla has a well developed cream coloured patination. It measures 33.77mm in diameter, 5.17mm in thickness, and weighs 29.8g.
