It's a bit difficult to determine who would have been suitable as the three female Worthies of the Pagan age, so I would suggest a slate of Greek (Atalante, Iphigenia, Penelope, and Antigone) and Roman (Veturia and Cornelia Africana) women. The Jewish women, I think, would be Ruth, Deborah, and Judith, or possibly Esther in lieu of one of the other three. No grouping of female Worthies in the Christian era could fail to include the Blessed Virgin Mary; I would suppose the others might be Mary Magdalene, Helena, Clotilda, Matilda, Eleanor of Aquitaine, or Joan of Arc.
