Anthony Etherin is a UK-based writer of constrained, formal and experimental poetry. He is known for composing poems that combine various forms of literary constraint, such as anagrammed palindromes and palindromic sonnets. He is the inventor of the aelindrome, a new lettristic constraint, in which letters are parsed according to premeditated, palindromic numerical sequences.
