The letters ſ and s
From the beginning of printing until towards the end of the eighteenth century ſ was used initially and medially and s finally, following of course the practice of the MSS. There were certain exceptions: Sweynheim and Pannartz, setting up the first press in Italy at Subiaco in 1465, used a type transitional in character though with marked gothic features, which used the long ſ in all positions, a practice which may have been imitated from Neapolitan MSS. of the period. Other printers sometimes followed the same usage in Roman type.
