The fifteenth century Florentine architect, whose 16th century was the most important for development in the sixteenth century, was Giuliano da Sangallo. From 1464 to 1472, he worked in Rome, where he made a number of cautious pictures after the city's ancient monuments, many of whom have been lost today and are well known on his work. Back in Florence, he became Lorenzo the Magnificent, a great humanist and favorite of the patron of the arts. Soon after completing Country Villa for Lorenzo in the beginning of the 1480s, Giuliano introduced a model for the proto new church near Florence, on which he began to work in 1485. In 1484, a child claimed that the wall of the Virgin's painting city's prison wall came to life, and soon the plans were made to remove the image and preserve it in a congregation, named Santa Maria delle Carceri.
Basilica's long novel was made for local churches due to the need to include illusion and the need to gather congregations, but the voter church became a natural topic for the Renaissance experiment with a central plan.
The current tradition of central-planning churches was extended to the early Christian martyrium and, ultimately, the classical Tholos or the circular temple. In his treatise on architecture, Alberti called the mediated plan ideal, which is derived from human belief that the circle was a symbol of divine perfection and both circles are included in a square and the cross included in the circle is the sign of the Cosmos. Thus, the church of Giuliano's is built on the Santa Maria delle Carceri, Greek-cross plan, it is one of the best early renaissance examples of humanitarian symbolism in architecture design.
