Valentina comes from the Latin valens, meaning strong or healthy, and the name is traditionally associated with vigor and robust vitality rather than delicacy. It's often read as suggesting resilience of body and spirit together -- strength understood as a kind of wellbeing, not merely physical force applied outward.
When a Planet who is a Fortune is in Conjunction with an Infortune, he allays his malice, so that the Infortune shall do no hurt. - William Lilly (1602.-1681.)
