The following chronologies of the two works in plaster by Umberto Boccioni, Unique Forms of Continuity in Space and Development of a Bottle in Space, as well as their castings, and of the work by Marino Marini, Great Horse, were developed through a research based on documentation available at the Museum of Contemporary Art of the University of São Paulo itself, in its cataloging section, and researched material in the archives of the Fundação Bienal de São Paulo, as well as based on confrontation of literature available on the subject.

There is no catalog raisonné of the work by Umberto Boccioni and the information about the casts are scarce and scattered. This chronology intends to gather and confront all this information in one place, so to work as a reference for future research.

In the case of the work by Marino Marini, the control of the casts seems easier, for they were in the majority, as in the case of the work of the MAC USP, accompanied by the artist. We know that only three castings in bronze were made and that the plaster seems to have been destroyed by the artist himself.
