CHAPTER XI
WOMEN AS INSPIRERS AND COLLABORATORS IN SCIENCE
One of the most interesting literary figures of the fifth century was Caius Apollinaris Sidonius, who, after holding a number of important civil offices, became the bishop of Clermont. The most valuable of his extant works are his nine books of letters which are a mine of information respecting the history of his age and the manners, customs and ideals of his contemporaries.
In one of these letters, addressed to Hesperius, a young friend of his who exhibited special talent in polite literature, he expresses a sentiment which applies as well to the votary of science as to the man of letters. Referring to the assistance which women had given to their husbands and friends in their studies, he conjures him to remember that in days of old it was the wont of Martia, Terentia, Calpurnia, Pudentilla and Rusticana to hold the lamp while their husbands, Hortensius, Cicero, Pliny, Apuleius and Symmachus, were reading and meditating.[233]
