teer · the swift one, the scribe · Mercury
The name of Mercury in your ancestral chart - the way of thinking your grandparents left in you.
The short answer
Tir is the Zoroastrian name for Mercury, and in Horospire's ancestral system it names the third generation - your grandparents. Your Mercury sign describes how your mind works: how you think, learn, and put things into words. Read generationally, it is the intellectual blueprint your grandparents passed forward into the way you reason.

The definition
Tir governs your mind, communication, and learning style - the way of thinking your grandparents handed down.
How your mind works, your natural thinking style, how you learn, and how you express yourself - the intellectual blueprint from your grandparents.
The planet
Mercury is the planet of mind and message: how you process information, form thoughts, and communicate. It is the wiring behind the way you reason and speak.
The inheritance
As the third generation, Tir carries your grandparents. Mercury's sign is where their patterns of thought echo in you - the family way of arguing, learning, storytelling, or staying silent. It is the intellectual grain of the lineage, three generations deep.
How to read it
Read your Mercury sign as an inherited style of thinking. Ask whether your default way of reasoning is genuinely yours or a habit of mind that runs in the family - once you can see it, you can choose when to keep it and when to think differently.
Tir is the Middle Persian name associated with Mercury and with Tishtrya, the swift star-divinity of Zoroastrian tradition. Its associations of speed, writing, and messengership map onto Mercury and onto the transmitted, learned inheritance of the grandparents. The mapping of the seven planets onto seven ancestral generations is Horospire's interpretive framework, rooted in the Zoroastrian Fravashi tradition, and offered as a reflective lens rather than proven science.
