What Venus does in a chart
Venus is the part of the chart that answers one question:What do I find beautiful, and how do I show affection? It describes love style — not events, and not outcomes.
What Taurus does to it
Taurus is a earth sign, so it moves on evidence and consistency. It is also fixed, which means it holds things. Put those together with Venus and you get loves through the senses — steady, sensory, loyal, applied specifically to love style.
Taurus is ruled by Venus, so this placement tends to be coloured by love style as well.
The useful version
Placements are not verdicts. This one describes a default setting, not a limit — the things listed above are what you do when you are not thinking about it, which is exactly why noticing them is worth something.
