In addition to the grid, the first edition of "Documents in Mycenaean Greek" contained a number of other signs termed "homophones" because they appeared at that time to resemble the sounds of other syllables and were transcribed accordingly: "pa2" and "pa3" were presumed homophonous to "pa". Many of these were identified by the second edition and are shown in the "special values" below. The second edition relates: "It may be taken as axiomatic that there are no true homophones." The unconfirmed identifications of "*34" and "*35" as "ai2" and "ai3" were removed. "pa2" became "qa".
