 It features many tengwar shapes, the inherent vowel found in some tengwar varieties, and the tables in the samples V12 and V13 show an arrangement that is very similar to one of the primary tengwar in the classical Quenya "mode".Jim Allan ("An Introduction to Elvish", ) compared the tengwar with the "Universal Alphabet" of Francis Lodwick of 1686, both on grounds of the correspondence between shape features and sound features, and of the actual letter shapes.The tengwar were probably developed in the late 1920s or in the early 1930s.
