Tractatus de proprietatibus quarundam stellarum et convenentia earundem quibusdam lapidibus et herbis

In the XXXII chapter of the secondo book of De occulta philosophia Cornelius Agrippa quotes an advice by the Arabian astronomer Thabit, about how to capture a specific star virtus, by picking up the stone and the herb associated to it, when the Moon stands in good aspect with the star itself.
