every
matter, the father and son set their hands to the work; and, while
they were engaged upon it, Mosca was very helpful and useful to that
city, making for many citizens architectural designs of houses and
many other edifices. Among other things, he executed in that city the
ground-plan and facade of the house of Messer Raffaello Gualtieri,
father of the Bishop of Viterbo, and of Messer Felice, both noblemen
and lords of great excellence and reputation; and likewise the
ground-plans of some houses for the honourable Counts della Cervara.
He did the same in many places near Orvieto, and made, in particular,
the models of many structures and buildings for Signor Pirro Colonna
da Stripicciano.

The Pope then causing the fortress to be built in Perugia where
there had stood the houses of the Baglioni, Antonio da San Gallo,
having sent for Mosca, gave him the charge of making the ornaments;
where there were executed after his designs all the doors, windows,
chimney-pieces, and other suchlike things, and in particular two large
and very beautiful escutcheons of his Holiness. In that work Simone
formed a connection with M. Tiberio Crispo, who was Castellan there;
and he was sent by M. Tiberio to Bolsena, where, on the highest point
of that stronghold, overlooking the lake, he arranged a large and
beautiful habitation, partly on the old structure and partly founding
anew, with a very handsome flight of steps and many ornaments of
stone. Nor did any long time pass before Messer Tiberio, having been
made Castellan of the Castello di S. Angelo, caused Mosca to go to
Rome, where he made use of him in many matters in renovating the
apartments of that castle; and, among other things, he caused him to
make over the arches that rise over the new loggia, which faces
towards the meadows, two escutcheons of the above-named Pope in
marble, which are so well wrought and perforated in the mitre, or
rather, triple crown, in the keys, and in certain festoons and little
masks, that they are marvellous.

Having then returned to Orvieto in order to finish the work of the
chapel, he laboured there continuously all the time that Pope Paul was
alive, executing it in such a manner that it proved to be, as may be
seen, no less excellent than the first, and perhaps even better. For
Mosca, as has been said, bore such love to art, and took such pleasure
