religion into all his conquests, obliging the _Saxons_ and _Hunns_ who were
heathens, to receive the _Roman_ faith, and distributing his northern
conquests into Bishopricks, granting tithes to the Clergy and _Peter-pence_
to the Pope: by all which the Church of _Rome_ was highly enlarged,
enriched, exalted, and established.

In the forementioned _dissertation upon some coins of _Charles_ the great,
_Ludovicus Pius_, _Lotharius_, and their successors, stamped at _Rome__,
there is a draught of a piece of _Mosaic_ work which Pope _Leo_ III. caused
to be made in his Palace near the Church of _John Lateran_, in memory of
his sending the standard or banner of the city of _Rome_ curiously wrought,
to _Charles_ the great; and which still remained there at the publishing of
the said book. In the _Mosaic_ work there appeared _Peter_ with three keys
in his lap, reaching the _Pallium_ to the Pope with his right hand, and the
banner of the city to _Charles_ the great with his left. By the Pope was
this inscription, SCISSIMUS D.N. LEO PP; by the King this, D.N. CARVLO
REGI; and under the feet of _Peter_ this, BEATE PETRE, DONA VITAM LEONI PP,
ET BICTORIAM CARVLO REGI DONA. This Monument gives the title of King to
_Charles_, and therefore was erected before he was Emperor. It was erected
when _Peter_ was reaching the _Pallium_ to the Pope, and the Pope was
sending the banner of the city to _Charles_, that is, A.C. 796. The words
above, _Sanctissimus Dominus noster Leo Papa Domino nostro Carolo Regi_,
relate to the message; and the words below, _Beate Petre, dona vitam Leoni
Papæ & victoriam Carolo regi dona_, are a prayer that in this undertaking
God would preserve the life of the Pope, and give victory to the King over
the _Romans_. The three keys in the lap of _Peter_ signify the keys of the
three parts of his Patrimony, that of _Rome_ with its Duchy, which the Pope
claimed and was conquering, those of _Ravenna_ with the Exarchate, and of
the territories taken from the _Lombards_; both which he had newly
conquered. These were the three dominions, whose keys were in the lap of
