START:*HYPOTHESIS: Isaiah's time as prophet began with his prophecy in ISA 6:1 the year Uzziah died. [Shulman date p83] [Ussher date p76] END:*EXTRA-BIBLICAL HISTORY: The Talmud (Yevamot 49b-50a) and later Christian texts like the “Martyrdom of Isaiah” (a 2nd-century BC apocryphal work), claim Isaiah was martyred by being sawn in two under King Manasseh’s orders. This tradition is reflected in Hebrews 11:37. *HYPOTHESIS: This happened at the beginning of Manasseh's reign. [Shulman date p83] [Ussher date p86]

Years are anno hominis — counted from Creation as year 1 — which is the frame the source computes in. The arithmetic behind each boundary is given above rather than assumed.
