「神曲之父」韓德爾 (Georg Friedrich Händel, 1685-1759) 應有資格作為一位歌劇作曲家被後世加以討論，他的一生有38年的時間在從事歌劇創作。雖然他的歌劇並未受到同時代觀眾的重視，而且在歌劇的發展史中也一度被人遺忘，但他留下的許多歌劇詠歎調傳唱至今仍不衰。 本論文乃是針對巴洛克時期知名作曲家韓德爾的歌劇作品進行綜合性的研究，研究重點放在目前已有DVD影音出版品的十部韓德爾歌劇，所涉及的研究範疇涵蓋韓德爾的歌劇生涯、創作規劃、結構上的特色、劇本取材、人聲運用與聲樂形式、樂器運用與器樂形式以及十部歌劇DVD的詳細介紹與樂評。筆者希望透過具體作品的觀察與分析，能夠對於韓德爾的歌劇藝術與巴洛克時期的歌劇有著更進一步的了解，並試圖觀察其中的藝術價值和深度，進而增加對這些作品的理解與欣賞。 The master of oratorio, Georg Friedrich Händel (1685-1759), who devoted thirty eight years to composing opera, is the renowned representative deserving discussion as an opera composer.
