===1401 competition===
In 1401, the [[Arte di Calimala]] (Cloth Importers Guild) announced a competition to design doors that eventually would be placed on the ''north side'' of the baptistry. The original location for these doors was the east side of the baptistry, but the doors were moved to the north side of the baptistry after Ghiberti completed his second commission, known as the "Gates of Paradise".<ref>See Laurie Schneider Adams, Italian Renaissance Art, (Boulder, Colorado: Westview Press, 2001), 60. Actually, at the time of the 1401 competition the Florence baptistry needed two portals to be decorated. The aim of the 1401–02 competition was to begin work on this project.

These new doors would serve as a votive offering to celebrate Florence being spared from relatively recent scourges such as the [[Black Death]] in 1348. Each participant was given four tables of brass, and was required to make a relief of the “Sacrifice of Isaac” on a piece of metal that was the size and shape of the door panels.<ref name=":0" /> Each artist was given a year to prepare their panel, and the artist who was judged the best was to be given the commission.<ref name=":0" /> While many artists competed for this commission the jury selected only seven semifinalists which included Ghiberti, [[Filippo Brunelleschi]], Simone da Colle, Francesco di Val d’Ombrino, [[Niccolò d'Arezzo|Niccolo d’ Arezzo]], Jacopo della Quercia da Siena, and [[Niccolò Lamberti|Niccolo Lamberti]].<ref name=":0" /> In 1402 at the time of judging, only Ghiberti and Brunelleschi were finalists, and when the judges could not decide, they were assigned to work together on them. Brunelleschi's pride got in the way, and he went to Rome to study architecture, thereby leaving the then 21-year-old Ghiberti to work on the doors himself. Ghiberti's autobiography, however, claimed that he had won, "without a single dissenting voice." The original designs of ''The Sacrifice of Isaac'' by Ghiberti and Brunelleschi are on display in the museum of the [[Bargello]] in Florence. Differences between the ''Sacrifice of Isaac'' created by Brunelleschi and Ghiberti include the way that the panel was constructed and the overall efficiency of the panel. Brunelleschi's panel consisted of individual pieces of the figures of the artwork being placed onto the bronze framework. In contrast to Brunelleschi's method of creating the artwork on his panel, Ghiberti's casting of the art had all of the figures, with the exception of Isaac, created as one piece.<ref>{{Cite thesis|last=Gregory|first=E.M.|date=2014|title=Storytelling in Bronze: The Doors of the Baptistery of San Giovanni as Emblems of Florence's Roman History and Artistic Progression|type=BA thesis|publisher=College of William & Mary|url=https://scholarworks.wm.edu/honorstheses/31/|archive-url=https://web.archive.org/web/20190102143138/https://scholarworks.wm.edu/cgi/viewcontent.cgi?referer=&httpsredir=1&article=1031&context=honorstheses|archive-date=2019-01-02|pages=28–29}}</ref>{{better source needed|date=April 2023}} The pieces of the figures themselves were all hollowed out on the inside. Due to the methods of how Ghiberti made the panel, it ended up being stronger, used less bronze, and had less weight than Brunelleschi's panel. By using less bronze, the panels were also more cost efficient. Including the aspect of the art itself, these differences were included on how the council of the competition decided on the victor.

==== After the competition ====
After the competition, Ghiberti's father Bartolo assisted him greatly in perfecting the design of his door before it was cast.<ref name=":0" /> This commission brought immediate and lasting recognition to the young artist. In 1403 the formal contract was signed with Bartolo di Michele's workshop, the same workshop he had previously been trained in, and overnight it became the most prestigious in Florence.<ref name=":0" /> Four years later in 1407, Lorenzo legally took over the commission and was prohibited from accepting additional commissions. He devoted much of his time to creating the gates, and was paid two-hundred florins a year for his work.<ref name=":0" /> To cast the doors, Lorenzo worked in a studio named the Aja or Threshing floor. The studio was located near the [[Hospital of Santa Maria Nuova|Hospital of Saint Maria Nuova]], the oldest hospital that is still active in Florence today.<ref name=":0" /> At the Aja, Ghiberti built a large furnace to melt his metal in an attempt to cast the doors, however his first model was a failure. After this trial, he attempted once more to make a mold. On his second try he was successful and ended up using 34,000 pounds of bronze, costing a total of 22,000 ducats.<ref name=":0" /> This was a large sum in this time period.

It took Ghiberti 21 years to complete the doors. These gilded bronze doors consist of twenty-eight panels, with twenty panels depicting the life of Christ from the [[New Testament]], and on April 19, 1424 they were placed on the side of the Baptistery.<ref name=":0" /> Twenty panels showing the life of Christ from the New Testament are depicted: the ''Annunciation, Nativity, Adoration of the Magi, Dispute with the Doctors, Baptism of Christ, Temptation of Christ, Chasing the Merchants Away, Christ Walking on Water, Transfiguration, Resurrection of Lazarus,'' ''Christ’s Arrival in Jerusalem, Last Supper, Agony in the Garden, Christ Being Captured, Flagellation, Christ on Trial with Pilate, Trip to Calvary, Crucifixion, Resurrection, and Pentecost.''<ref>{{Cite web|url=http://www.guildofthedome.com/projects/baptistery-doors/north-door/the-panels.php|title=Florence Baptistery - North Door - The Panels|website=www.guildofthedome.com|access-date=2018-04-24}}</ref> The eight lower panels show the four evangelists and the Church Fathers: Saint Ambrose, Saint Jerome, Saint Gregory and Saint Augustine. The panels are surrounded by a framework of foliage in the door case and gilded busts of [[prophet]]s and [[sibyl]]s at the intersections of the panels. Originally installed on the east side in place of Pisano's doors, they were later moved to the north side. They are described by the art historian [[Antonio Paolucci]] as "the most important event in the history of Florentine art in the first quarter of the fifteenth century".<ref>Antonio Paolucci (1996), "The Origins of Renaissance Art: The Baptistery Doors, Florence" 176 pages; Publisher: George Braziller; {{ISBN|0-8076-1413-0}}</ref>

The bronze statues over the northern gate depict ''John the Baptist preaching to a Pharisee and Sadducee'' and were sculpted by [[Francesco Rustici]]. Rustici may have been aided in his design by [[Leonardo da Vinci]], who assisted him in the choice of his tools.

==== After completion of the doors ====
After the completion of these doors, Ghiberti was widely recognized as a celebrity and the top artist in this field. He was given many commissions, including some from the pope. In 1425 he got a second commission for the Florence Baptistery, this time for the ''east doors'', on which he and his workshop (including [[Michelozzo]] and [[Benozzo Gozzoli]]) toiled for 27 years, excelling themselves. The subjects of the designs for the doors were chosen by [[Leonardo Bruni|Leonardo Bruni d'Arezzo]], then chancellor of the Republic of Florence.<ref>{{cite book|chapter=Chapter III. Baptistery Doors|last=Scott|first=Leader|author-link=Lucy Baxter|title=Ghiberti and Donatello|year=1882|page=[https://archive.org/details/ghibertianddona01scotgoog/page/n78 65]|location=London|publisher=Sampson Low, Marston, Searle, & Rivington|url=https://archive.org/details/ghibertianddona01scotgoog}}</ref> They have ten panels depicting scenes from the [[Old Testament]], and were in turn installed on the east side. The panels are large rectangles and were no longer embedded in the traditional Gothic quatrefoil, as in the previous doors. Ghiberti employed the recently discovered principles of perspective to give depth to his compositions. Each panel depicts more than one episode. "The Story of Joseph" portrays the narrative scheme of ''Joseph Cast by His Brethren into the Well'', ''Joseph Sold to the Merchants'', ''The merchants delivering Joseph to the pharaoh'', ''Joseph Interpreting the Pharaoh's dream'', ''The Pharaoh Paying him Honour'', ''Jacob Sends His Sons to Egypt'' and ''Joseph Recognizes His Brothers and Returns Home''. According to [[Vasari]]'s ''[[Lives of the Most Excellent Painters, Sculptors, and Architects|Lives]]'', this panel was the most difficult and also the most beautiful. The figures are distributed in very low relief in a perspective space (a technique invented by Donatello and called ''rilievo [[schiacciato]]'', which literally means "flattened relief"). Ghiberti uses different sculptural techniques, from incised lines to almost free-standing figure sculpture within the panels, further accentuating the sense of space.

The panels are included in a richly decorated gilt framework of foliage and fruit, with many statuettes of prophets and 24 busts. The two central busts are portraits of the artist and of his father, Bartolomeo Ghiberti.

The ''Annunciation'' panel portrays the scene with an angel dressed in robe, wings, and a trumpet appearing to Mary, which was shown in an expression of shock leaving a doorway.<ref>{{Cite web|url=http://www.guildofthedome.com/projects/baptistery-doors/north-door/panel-detail.php?proj=1&seq=0|title=The North Door Panels|website=www.guildofthedome.com|access-date=2018-04-24}}</ref> The ''Nativity'' panel depicts the birth of Christ with an ox, a donkey, Joseph and Mary, an angel, and the shepherds.

[[Michelangelo]] referred to these doors as fit to be the "Gates of Paradise" (It. ''Porte del Paradiso''), and they are still invariably referred to by this name. [[Giorgio Vasari]] described them a century later as "undeniably perfect in every way and must rank as the finest masterpiece ever created". Ghiberti himself said they were "the most singular work that I have ever made".
