Gaspare Celio (1571–1640) was an Italian painter of the late-Mannerist and early-Baroque period, active mainly in his native city of Rome.
His first commissions in about 1596 were completed with Giuseppe Valeriano who asked Celio to decorate the Chapel of the Passion in the church of il Gesù in Rome.[1] He also paints a Madonna and Bambino, now in Santa Maria del Carmine, a Passagge through the Red Sea (1607), and for the Palazzo Mattei, la Death of the Giants
Between 1620 -1638 he helps publish a guide to the churches and artwork in Rome (Memoria delli nomi dell'artefici delle pitture che sono in alcune chiese, facciate e palazzi di Roma). He briefly worked in Parma as a painter for the court of Ranuccio Farnese.
