Just had a browse of Wikipedia and am now more confused. It states that the consonants of https://en.wikipedia.org/wiki/Romic_alphabet https://en.wikipedia.org/wiki/Romic_alphabet are the same as were adopted by IPA, except "⟨ñ ᵹ ɹ λ ꞁ⟩ were eventually replaced with ⟨ɲ ɣ ʕ ʎ ʟ⟩ in the IPA". No mention of ⟨θ⟩ in that sentence. However, looking at the table on that page, the "th" in "think" is represented by ⟨þ⟩! Going back to the first version of IPA on https://en.wikipedia.org/wiki/History_of_the_International_Phonetic_Alphabet https://en.wikipedia.org/wiki/History_of_the_International_P... the "th" in "think" is represented by ⟨θ⟩. Looking at the other two major early influences mentioned in that article, https://en.wikipedia.org/wiki/English_Phonotypic_Alphabet https://en.wikipedia.org/wiki/English_Phonotypic_Alphabet and https://en.wikipedia.org/wiki/Palaeotype_alphabet https://en.wikipedia.org/wiki/Palaeotype_alphabet neither uses ⟨θ⟩ for that sound either. By the looks of it, English Phonotypic Alphabet uses a capital theta to represent a vowel sound!
