The international Film Festival Religion Today has chosen Marcello's painting of "Abraham counting the stars" for its poster of the XXVI edition (13-20 September 2023). This picture fully speaks to the interfaith spirit that animates the festival. The event also hosts a presentation of Marcello's latest book Sapienza Antica Arte Contemporanea (Claudiana 2023) on Saturday 16/09/2023 inside the "Tenda di Abramo" (Abraham's tent), in Cesare Battisti square in Trento, Italy. Introduction by Mgr Luigi Bressan, Archbishop emeritus of Trento.
