Another major development was the enormous growth of linguistic study on Homer and the Homeric dialect. In 1732, Bentley published his discovery of the traces left in the text of Homer by the digamma, an archaic Greek consonant that was omitted in later, classical, Greek orthography. Bentley showed conclusively that the vast majority of metrical anomalies in Homeric verse could be attributed to the presence of digamma (though the idea was not well received at the time: Alexander Pope, for one, satirised Bentley). Important linguistic studies continued throughout the next two centuries alongside the endless arguments over the Homeric question, and the work by figures such as Buttmann and Monro is still worth reading today; and it was the linguistic work of Parry that set in motion a major paradigm shift in the mid-20th century. Another major 18th century development was Villoison's 1788 publication of the A and B scholia on the "Iliad".
