At the present time, so far as the Roman Catholic Church is concerned, apparelled albs are only in regular use at Milan (Ambrosian Rite), and, partially, in certain churches in Spain.
The gospel and epistle are still read from the ambo in the Ambrosian rite at Milan.
In that year, however, Angelo Mai discovered in the Ambrosian library at Milan a palimpsest manuscript (and, later, some additional sheets of it in the Vatican), on which had been originally written some of Fronto's letters to his royal pupils and their replies.
The political events of 1808 necessitated his withdrawal from Rome (to which he had meanwhile returned) to Milan, where in 1813 he was made custodian of the Ambrosian library.
His nephew, Federigo Borromeo (1564-1631), was archbishop of Milan from 1595, and in 1609 founded the Ambrosian library in that city.
