Final answer:
Ana Mendieta's Silueta Series, Vito Acconci's Following Piece, and Marina Abramović's The Artist is Present all use the artist's own body as a central theme of the work, emphasizing engagement with nature, the audience, and the environment to explore themes like identity and the human condition.
Step-by-step explanation:
How Ana Mendieta’s Silueta Series is similar to Vito Acconci’s Following Piece and Marina Abramović’s The Artist is Present lies in the use of the artist's body as a central subject of their artworks. Mendieta's work in particular presents strong connections with nature and feminist themes, with her Silueta Series blending Land Art and Body Art, creating female silhouettes in natural environments and photographing them.
Both Abramović and Acconci use their own bodies as part of their performance art, emphasizing engagement and interaction with the audience or the surrounding environment, suggesting a blurring of the boundaries between the artist and the artwork itself.
While the artistic expressions of Mendieta, Acconci, and Abramović are diverse, they all share a common thread of utilizing the human form as an integral part of their work, allowing viewers to consider deeper themes of identity, presence, and the human condition.
