This Index owes its origin to the deciphering of a folio printed in Greek in Paris in 1628. As other books came under my eye, I found that in addition to the ligatures which I had analysed there were still many others, and I was so beguiled by their manifold and often obscure forms that I went far afield in my researches. It was surprising, no less than disconcerting, that with the exception of Proctor, to whom reference will presently be made, no one in modern days had occupied himself with a phase of Greek typography which, owing to its crabbedness and elusive contractions, based no doubt upon the Tironian practices of the scribes, had estranged students from the study of later Greek literature.

Beginning with the Baskerville fount of 1763, I worked backwards, overtaking the Paris fount, till, with a Froben as a complication, I was entangled in an Aldine. This led me to Proctor's erudite monograph on The Printing of Greek in the Fifteenth Century, which was of great value, for by its means I was able to verify my own decipherings and at the same time to add to my list fresh examples from the texts and founts which he had analysed.

Apart from Proctor's work only three lists were accessible. The first was that of Aldus Manutius (1494–5), who gave clues to the more complicated sorts in one of his founts, adding that he passed over many ‘connexiones’ as they could be identified very easily. The next list was that printed at the end of the Greek Grammar of Ramus (Hanover, 1605), in which the Aldine ‘connexiones’ were included and others as well, a thoughtful proceeding if the Grammar was to be of any use, for it was printed almost entirely in ligatures.
