Some astrologers have said that the Anti-Vertex is less significant than the Vertex, but based on personal experience, as well as my observations of other synastry charts, I disagree. What is the difference between the Vertex and Anti-Vertex? The Vertex is considered a “second Ascendant,” while the Anti-Vertex is considered a “second Descendant.” As such, Vertex connections in synastry signify a highly personal connection.
Indeed, Composite Charts featuring a Vertex/Descendant conjunction are common among married, fated, “meant-to-be” relationships. Strong Vertex and Anti-Vertex aspects in the Composite chart also indicate a fated union. In my article which looked at common Synastry Aspects in the charts of married couples, I noticed the Vertex and/or Anti-Vertex of at least one of the partners was often activated. When your Vertex is contacted by another person’s planet or point, a fated relationship is indicated.
