The decoration of the dome arch
(The Redeemer and Moses, Sphinx, and Archangels)
All stone inventories are also reliefs and the decoration
of the dome arch, originally conceived as a mosaic
and then as a fresco, has been left unfinished. Plywood
boards with representations of The Redeemer
(oil) and Moses, Sphinx, and Archangels
(charcoal and crayon) are attached to the dome crown.
Ivan Mestrovic himself made the painting and the drawings,
while the reliefs and the sculptures were cast in
stone from his plaster casts (models) by his students
and sculptors Antun Augustincic, Grga Antunac, Vanja
Radaus, Ivo Lozica, Dragutin Orlandini, and Marijan
Matijevic, aided by three stonemasons.
