A more formal variant of anaglyphic, describing things related to anaglyphs or anaglyphic techniques.
Extended form of anaglyphic using the suffix -al, a common pattern in 19th and early 20th-century scientific terminology.
Like anagenetical, this is the fancy Victorian-era version of a simpler word—anaglyphical and anaglyphic mean the same thing, but the longer version sounds more authoritative in old scientific papers.
