Per il testo di Servio, GL IV 437, 34-36

The paper argues that in Servius, Commentarium in Donatum GL IV p. 437, 34-36 (septem litteras non habet, h o f K q y z), 'h' should be changed to 'a', as a result of palaeographic confudion between letters a/h, which happened at some late-antique stage in the transmission of this work.
