Conrad Witz 's only existing and signed outdated work is the altarpiece of St. Peter's Basilica in St. Peter's Basilica in Geneva, Switzerland. It can only survive in part; one of the four surviving wings is an external panel that draws a magical fish scene. It was ordered by the Cardinal François Demis in 1443. Conrad Witt 's paintings represent many of the ideological changes that occurred during the Renaissance era. The draft of Witz's "Magical Fish" reflects changes in the view of naturalism in the Renaissance, the power of observation, the role of artists in depicting sacred objects, the composition of paintings, and the addition of companies.
The three main works are due to Giotto of Rome. They are the announcement of the walk of Christ on the water (Navicella), the large mosaic of the entrance to St. Peter's Basilica, the altarpiece of the Cardinal Stephaneeski (Vatican Museum), and the frescoes of Boniface VIII, Latrano (St. John). San Giovanni of Rutland. As everyone knows, Giot drew some murals on the old St. Peter's choir, but these murals have been lost. These Roman works also have problems with attribution and criticism. The affiliation of Navicella is positive; it is well known that Cardinal Stefaneschi asked Giotto to do so. But since the mosaic was reproduced nearly completely in the 17th century, except for the two fragmentary angel heads, old copies must be used for all interpretation styles.
In the "Biblical Archaeological Review" announced on 11th November 1993, Galileo fisherman Mendernin wrote that St. Peter's fish is also known to eat plankton. He believes that the Bible Saint Peter's fish is a squid-like thorn. Squid has recently been introduced in the lake, but the Ein Gev authority of the Galilee Fishery History Museum has identified the squid that was in the lake since ancient times. This is also posted in Mendelny's book. This small fish is a kind of fish feeding from the bottom, and when it is shiny it may be attracted to glossy ones. Mendel wrote that the fish is looking for a snail and removes the dead fish from the bottom sediment.
