Iscephaly
Isokephalie (from Greek ἴσος isos , "same" and κέφαλος Cephalus , "head"), also known as direct head height is known, a pictorial style means, preferably in the Romanic was used and predominantly in history paintings and icon representations is used. Ancient depictions also show iscephaly.
Iscephaly means that the heads of all or more of the figures shown are on the same level. If this apparently contradicts the actual circumstances (e.g. because one figure is shown seated, the others standing), the figure in question is displayed "larger than life" and thus emphasized. Iscephaly can also be produced by a graduated subsurface that compensates for the differences in size of the people.
