Ricci was born 6 October 1552, in Macerata, part of the Papal States, and today a city in the Italian region of Marche. He made his classical studies in his native town and studied law at Rome for two years. He entered the Society of Jesus in April 1571 at the Roman College. While there, in addition to philosophy and theology, he also studied mathematics, cosmology, and astronomy under the direction of Father Christopher Clavius. In 1577, he applied for a missionary expedition to the Far East. He sailed from Lisbon, Portugal in March 1578 and arrived in Goa, a Portuguese Colony, the following September. Ricci remained there employed in teaching and the ministry until the end of Lent, 1582, when he was summoned to Macau to prepare to enter China. Ricci arrived at Macau in the early part of August.
