Sisinnios 29 was patrikios and magistros; owner of a seal dateable to the late seventh or early eighth century: Seibt, Bleisiegel I, no. 78. Obv.: invocative monogram of Θεοτόκε βοήθει with the legend τω - σω - δου - λω. Rev.: +Σισι - ννιω πα - [τ]ρικιω (καὶ) - μαγης - τρω.

He was probably the owner of a second seal which closely resembles this one and is dated slightly later by Seibt, to the early eighth century: Zacos and Veglery 2370 (cited by Seibt, op. cit., p. 195). Obv.: invocative monogram of Θεοτόκε βοήθει with the legend τω - σω - δου - λω. Rev.: +Σισιννι - ω πατρικ - ιω (καὶ) μαγ[ι] - στρω+. He was a patrikios holding the post of magistros. He can not easily be identified with any of the other Sisinnioi known from this period. Cf. Sisinnios 1, Sisinnios 2, Sisinnios 3, Sisinnios 28.
