Historian Adam McLean has suggested that the garden is associated with the Rosicrucians, and "should be seen as an early 17th-century Mystery Temple". McLean describes the garden as a place of instruction, and remarks that the whole structure is reminiscent of "Eliphas Levi's description of the ancient Tarot of the Egyptians carved into the walls of their initiation temples, to which the candidate was taken to contemplate the sequence of the symbols". He backs up this suggestion with the observation that the Mantegna Tarocchi, a set of 15th-century engravings formerly thought to be a tarocchi or tarot deck, includes all these images amongst its symbols.
