Another form of Arcadian; relating to or characteristic of Arcadia or its idealized pastoral qualities.
From Arcadia + -ic suffix (an alternative to -ian for creating adjectives), giving the term a slightly different emphasis while maintaining the same meaning.
Using 'arcadic' instead of 'Arcadian' was partly just stylistic preference in English, but it shows how the same concept can be expressed through different grammatical formations—both forms existed comfortably in the same literary circles.
