On 31st January 828 the relics of the Patron Saint Mark were brought
from Alexandria, not without adventure, to Venice where they were received
by the Doge Giustiniano Particiaco.
In those days relics were a powerful social and economic unifier, attracting
pilgrims and merchants. So all relics were welcomed, and those of St.
Mark particularly so in Venice since it was precisely this saint who had
evangelised the people of the Veneto, becoming their patron saint and
emblem in the form of a winged lion armed with a sword, and with a book
in which the words Pax Tibi Marce Evangelista Meus (Peace to You Oh Mark
My Evangelist) could be read in peacetime, but which was closed threateningly
when the sword, rather than discriminating between good and evil, was
stained with the blood of war.
