My guess would be "windy-kay." In those days, Latin was far more prevalent in the schools, and the classical pronunciation would probably have been used.
There are some classical scholars who have made tapes of readings in Latin and Greek that they believe to be even closer to the original pronunciation than other scholars have used. There is a Society for the Oral Reading of Greek and Latin Literature. I'm not sure if there are any online readings that can be listened to for free. Robert P. Sonkowsky of the University of Minnesota and Stephen G. Daitz of the City University of New York are among those who do these readings.
