2 January 1645 – 8 January 1645

Was the ceremony of our Savior's baptism in the Church of St. Athanasius, and at Ara Celi was a great procession, del Bambino, as they call it, where were all the magistrates, and a wonderful concourse of people.

A sermon was preached to the Jews, at Ponte Sisto, who are constrained to sit till the hour is done; but it is with so much malice in their countenances, spitting, humming, coughing, and motion, that it is almost impossible they should hear a word from the preacher. A conversion is very rare.
