.- While Antonio Vivaldi's “Four Seasons” echoes in concert halls and elevators around the world, for some, his greatest masterpieces are not the scores resonating spring, summer, fall and winter, but rather his sacred music.

Although less known, Vivaldi's sacred music compositions, according to a researcher and expert on the musician's life, is probably his greatest contribution to music – featuring an altogether unprecedented combination of deep spirituality and the contemporary trends of the time.

And this profound personal spirituality was rooted in what is likely a little-known fact for many: Antonio Vivaldi was a Catholic priest.

“I'm going to give you the most bizarre idea. Think of the Pope, who represents priests, spiritual things, and then you've got Jimi Hendrix, a superb guitarist. You put them together and you've got Vivaldi,” British researcher Micky White told CNA Aug. 1.

It's a combination altogether “bizarre,” she said. “Vivaldi the priest, deeply spiritual, comes out in his music. Jimi Hendrix Vivaldi you've heard in the Four Seasons; it's the most bizarre piece of music.”

“It's timely, a priest wrote it,” and it's meshed with the modern style of the day – a combination of two things that are essentially “polls apart,” she said. “That's what makes him stand out among anybody. Bach wasn't a priest, Mozart wasn't a priest, nor was Beethoven, but Vivaldi was.

In listening to Vivaldi, it's obvious that he was a very faith-filled man, she said, “you hear it in his music, you listen to it.”

White, who left a thriving greeting card company in England and moved to Venice to pursue an increasing interest in researching Vivaldi's life, has become an expert and point of reference on the musician.

Not only has she published a book, “Antonio Vivaldi: A Life in Documents,” as the fruit of her research, but she was a consultant for a new display on his life called “Viva Vivaldi: The Four Seasons Mystery.”

The exhibit, located just behind St. Mark's Basilica in Venice, provides attendees with an indoor video-mapping show done with immersive HD images, surround sound and scent special effects such as scent and wind. It opened to the public May 13 at the Diocesan Museum, and will stay open during 2018.

One of the most famous Baroque composers, Antonio Lucio Vivaldi, affectionately known by many in his time as “the Red Priest” due to his auburn locks, was born in Venice in 1678.

His father, who was an instrumental figure in his life (pun intended), was a professional violinist, and taught his son how to play as a young child. The two then went on tour together throughout Venice, giving Vivaldi an extensive knowledge and even mastery of the violin from a young age.

In 1693, at the age of 15, he began studying for the priesthood. He was ordained in 1703 at the age of 25, and shortly after was appointed chaplain and Violin Master at a local orphanage called the Pio Ospedale della Pieta, or the Devout Hospital of Mercy.

The orphanage, called the “Pieta,” was founded in 1492 by a poor friar as a home for abandoned babies. Young children were typically raised by older girls already at the center, and while the boys were taught a specific trade and ousted at the age of 15, the girls were trained as musicians if they had the ability. If not, they were taught a different trade, such as reading or sewing.

The most talented of the girls stayed on and became members of the hospitals renown orchestra and choir. Vivaldi worked at the hospital from 1703-1715, when he was voted off the faculty. He was voted back in 1723, and remained until 1740, composing some of his most famous works during that time.

However, after just a year of being a priest, Vivaldi requested a dispensation form celebrating Mass due to his poor health. From birth he had been afflicted with a serious, unknown, health condition thought to be a form of asthma.

All that is known about the mysterious illness comes from the letter Vivaldi wrote asking for the dispensation, in which he referred to it as a “tightness of the chest.”

According to White, “it would have been very hard for Vivaldi to give up saying Mass. It would have been his own decision, a decision of nobody but himself, and he also gave up a good salary.”

She pointed to rumors alleging that he had been kicked out of the priesthood or even excommunicated, saying they “are so ignorant and so stupid,” because if one actually looks to the facts, the rumors are “not proven.”

She also addressed rumors that Vivaldi had abused the choir girls as the reason he was kicked off the Pieta faculty in 1715. These rumors, she said, “not only are they not true, they're impossible.”

Not only would Vivaldi have never been welcomed back in 1723, but many of the girls who remained in the orchestra stayed until they were 70 or even 80 years old. The hospital was also overseen by several governors, so had there been abuse, Vivaldi would have been kicked out right away, “so that doesn't add up,” White said.

People often make assumptions about the past or judge by their opinions, telling others that “'it must be like this' or 'so and so said that,'” White said, adding that when this happens “you go from bad to worse.”

But when she first started digging into her research on Vivaldi and putting the information into context, “then everything made sense,” she said, because “research is a matter of fact, it's not a matter of opinion, and it's not a matter of ideas, it's fact.”

She insisted that his priesthood was likely an essential element of his music. Even after stepping down from his liturgical duties, Vivaldi never stopped being a priest, White said. “Once a priest always a priest.”

“He was ordained, he was a priest his whole life (and) his spirituality comes out in his music, all you have to do is listen and you'll hear it.”

Although in poor health, Vivaldi made great strides in his musical career. He continued to write a variety of compositions, and received many commissions from all over Italy and Europe, for which he traveled frequently.

During one jaunt in 1722, Vivaldi moved to Rome, where he was invited to play for Pope Benedict XIII before moving back to Venice in 1725.

The various pieces he wrote throughout his career include several different types of concertos – from violin to orchestra – arias, sonatas, operas and sacred music.

But according to White, while the Four Seasons, written around 1721, and his many operas are what made Vivaldi rise to fame in his day, “sacred music is on another plane compared all the other compositions. It's the empire of composition itself that comes from faith.”

Among the sacred scores written by Vivaldi are the Gloria, the Credo, the Stabat Mater, the Magnificat, Dixit Dominus and Laetatus sum, among others. The “Laetatus sum,” specifically, was written by Vivaldi at the age of 13 in 1691.

White said that while these are the known liturgical and sacred works, “there's a lot, lot missing.”

Given his 38 year career at the hospital, there are likely many, many works of Vivaldi that have never been discovered, she said. For example, “I'm sure that he wrote full Masses, absolutely positive,” but they are likely all lost.

Despite the success he enjoyed during his career, Vivaldi died in poverty in Vienna July 28, 1741. He had moved to the Austrian country after meeting Emperor Charles VI, to whom he had dedicated his Opus 9 work, in 1728.

The emperor was so impressed with Vivaldi's work that he gave the musician the title of Knight, a gold medal and an invitation to Vienna. However, the emperor died shortly after Vivaldi's arrival several years later, and with no royal connection or steady income, Vivaldi became impoverished and died from an infection at the age of 63.

According to White, the greatest legacy that Vivaldi left can be summed up in one word: “music.”

“Music comes out of him, it doesn't come out of his brain, it just pours out of him. It's like a waterfall,” she said.

While his sacred and classical music might seem outdated in a society enthralled with artists such as Beyonce, Taylor Swift and Justin Bieber, White said Vivaldi is so versatile in his style that he can mesh with well with contemporary music as well as the older

“Vivaldi could do a rock concert quite easily, and Vivaldi can appeal to everyone,” she said. “Vivaldi, he's alone, he's absolutely unique. You talk about the Baroque style, and the romantic style...Vivaldi cuts that whole suede.”

With the “tremendous energy” present in his music, Vivaldi is truly one of a kind and is difficult to imitate, she said. “He doesn't fit anywhere, and he fits everywhere.”
