This paper examines the hitherto neglected resonance between Danto's and Derrida's concepts of the Artworld and the Frame. In doing so, I challenge prevalent understandings of Danto's theoretical framework, highlighting the necessary instability that he integrates into his definition of the art object. Equally, I emphasise the applicability of Derrida's deconstructive concept to the concrete conditions of contemporary artistic practice. I begin by examining the tensions present in Danto's definitional approach, as it demands a complex vision of Artworld relations. I (...) then consider how the ontologically constitutive character of Danto's Artworld may be re-examined through Derrida's concept of the parergon, as a supplementary techné that is fundamentally unstable and fragmented. Through this comparative reading I show that despite their different approaches, Danto's and Derrida's philosophies of art advance similar ontological conclusions. I thus argue that while their differences should not be minimised, our understanding of Danto's and Derrida's aesthetic concepts is enriched through recognition of their unforeseen correspondences.
