Short answers, pulled from the story.
The year 82 AD marks the completion of the Arch of Titus in Rome, which serves as the first prominent surviving example of the Composite order. Historical evidence suggests this architectural form was invented slightly before the reign of Augustus and well-developed before his death.
A typical column of the Composite order stands ten diameters high and combines the volutes of the Ionic order with the acanthus leaves found on the Corinthian order. The design removes the necessity for different appearances between front and side views unlike the Greek Ionic volute which shows unchanged width from side to back.
Leon Battista Alberti mentioned the Composite order in his work De re aedificatoria calling it Italic rather than giving it a distinct rank. Sebastiano Serlio published I Sette libri dell'architettura in 1537 becoming the second writer to mention the Composite order as its own entity.
Francesco Borromini developed the Composite order further in San Carlo alle Quattro Fontane in Rome starting in 1638 by placing inverted volutes underneath the arches. He took his radical modifications even further in the Oratorio dei Filippini lower order where he removed the acanthus leaves entirely.
Modern structures like the Alabama Governor's Mansion from 1907 continue to utilize this mixed architectural tradition across Europe and America. William Chambers designed Somerset House in London in 1776 incorporating these classical elements into its façade.
