In Peter Shaffer's Amadeus, which has much of a thematic and symbolic nature in common with its forerunners, Equus and The Royal Hunt of the Sun, stemming genetically from the unique sibling rivalry of twinship, there is more pronounced emphasis on the influence of envy and vengeance on human behavior than in the other two plays. It is postulated that the success of Equus and its implications pertinent to the competitive aspect of the relationship with his twin brother stirred appreciable intrapsychic turmoil in Shaffer and was a decisive motivating factor in his writing of Amadeus.
在彼得·谢弗的《莫扎特传》中，该剧在主题和象征意义上与其前作《马》和《太阳王的猎捕》有许多共同之处，其根源在于双胞胎独特的手足竞争关系，与其他两部戏剧相比，它更加强调嫉妒和复仇对人类行为的影响。据推测，《马》的成功及其与他双胞胎兄弟竞争关系相关的含义，在谢弗内心引发了相当大的心理动荡，这是他创作《莫扎特传》的决定性推动因素。
