Final answer:
The astronomical lens is not commonly used to interpret the myth of Prometheus, as it pertains to celestial bodies and is not relevant to this narrative which is better analyzed through feminist, psychological, or Marxist lenses.
Step-by-step explanation:
The lens that is NOT used to interpret Prometheus in the context of your unit is the Astronomical lens. When analyzing literature or a myth like Prometheus, feminist, psychological, and Marxist approaches represent distinct interpretive frameworks. The feminist lens looks at gender roles and power structures, the psychological lens delves into the mental states and subconscious motivations of characters, and the Marxist lens examines class struggles and socio-economic factors influencing a narrative. The astronomical perspective, however, concerns the study of celestial objects and would not typically be relevant for interpreting a myth unless the myth specifically dealt with astronomical themes or content, which is not the case with the story of Prometheus.
