The Assayer is published in 1623 as a dated public method-book on comets and experience

In 1623 The Assayer was published as Galileo's method-book on comets and experience. Grassi is the counterpart. It is not the 1632 Dialogue. Galileo Galilei's documented role is: He published Saggiatore against Grassi. Urban VIII as Barberini had been friendly; later Dialogue used that credit.

Context

Lincei printed. Sharing print with that academy is required.

The contribution type is direct. That reading is an impact-path choice, not a property stored on the Fact itself.

Confidence is stated on the impact path, not hidden in adjectives. Two books. Mixed effects of The Assayer is published in 1623 as a dated public method-book on comets and experience are separate paths.

Shared responsibility is part of The Assayer is published in 1623 as a dated public method-book on comets and experience. Naming Galileo Galilei does not delete co-authors, institutions, or later transmitters. The lag from 1623-01-01 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them.
