 In the procession on the righthand hill a giraffe rendered with noteworthy realism can be seen (a giraffe had been presented to Lorenzo de' Medici and brought to Florence in 1486).This scene was the one that Vasari, in his biography of Ghirlandaio, considered the best in the cycle, due to its dramatic and frantic composition.It is probable that Ghirlandaio was inspired by scenes of ancient Roman bas-reliefs, like that depicted on the arch in the background.
