The Composite order is a mixed order, combining the volutes of the Ionic order capital with the acanthus leaves of the Corinthian order. In many versions the composite order volutes are larger, however, and there is generally some ornament placed centrally between the volutes. The column of the composite order is typically ten diameters high, though as with all the orders these details may be adjusted by the architect for particular buildings. The Composite order is essentially treated as Corinthian except for the capital, with no consistent differences to that above or below the capital.

The Ospedale degli Innocenti 'Hospital of the Innocents', also known in old Tuscan dialect as the Spedale degli Innocenti, is a historic building in Florence, Italy. It was designed by Filippo Brunelleschi, who received the commission in 1419 from the Arte della Seta. It was originally a children's orphanage. It is regarded as a notable example of early Italian Renaissance architecture. The hospital, which features a nine bay loggia facing the Piazza SS. Annunziata, was built and managed by the "Arte della Seta" or Silk Guild of Florence. That guild was one of the wealthiest in the city and, like most guilds, took upon itself philanthropic duties.
