What roman author described the technique of Opus quadratum?
Vitruvius Marcus Vitruvius Pollio (born c. 80–70 BC, died after c. 15 BC), commonly known as Vitruvius, was a Roman author, architect, civil engineer and military engineer during the 1st century BC, known for his multi-volume work entitled "De architectura". His discussion of perfect proportion in architecture and the human body, led to the famous Renaissance drawing by Da Vinci of "Vitruvian Man".
Te Deum (Berlioz) The Te Deum (Op. 22 / H.118) by Hector Berlioz (1803–1869) was completed in 1849. Like the earlier and more famous ""Grande Messe des Morts"", it is one of the works referred to by Berlioz in his Memoirs as "the enormous compositions which some critics have called architectural or monumental music." While the orchestral forces required for the "Te Deum" are not as titanic as those of the "Requiem", the work calls for an organ that can compete on equal terms with the rest of the orchestra. It lasts approximately fifty minutes and derives its text from the traditional Latin Te Deum, although Berlioz changed the word order for dramatic purposes.
