Donatello was inspired by his contemporary Filippo Brunelleschi’s exploration into a linear perspective system involving orthogonals (diagonal lines that meet at a central vanishing point) and transversals (the lines crossing these orthogonals) which work together to draw the eye to the vanishing point and create an illusion of space on a two-dimensional surface.
Donatello je bio inspiriran istraživanjem njegovog suvremenika Filippa Brunelleschija o linearnom sustavu perspektive koji uključuje ortogonalne (dijagonalne linije koje se susreću na središnjoj nestašnoj točki) i transverzalne linije (linije koje prelaze ove ortogonalne) koji rade zajedno kako bi privukli oko u nedogled i stvorili iluziju prostora na dvodimenzionalnoj površini.
