Asīnum may have been mentioned (name completely restored) in VAT 9812 [http://oracc.museum.upenn.edu/riao/kinglists/fragmentvat9812/index.html#List], a fragmentary Assyrian king list discovered at Aššur that deviates significantly from the better preserved copies of the Assyrian King List [http://oracc.museum.upenn.edu/riao/kinglists/assyriankinglist/index.html] (AKL). From that document, assuming that the restoration of his name proves correct, it is presumed that Asīnum was the last member of the dynasty of Samsī-Addu I [http://oracc.museum.upenn.edu/riao/fromsamsiaddutomittanicilent18081364bc/samsiaddudynasty/samsiaddui/index.html] (see below); he is named in this fragmentary text together with two other successors of Išme-Dagān I [http://oracc.museum.upenn.edu/riao/fromsamsiaddutomittanicilent18081364bc/samsiaddudynasty/ishmedagani/index.html] not included in the "standard" version of the AKL, Mut-aškur [http://oracc.museum.upenn.edu/riao/fromsamsiaddutomittanicilent18081364bc/samsiaddudynasty/mutashkur/index.html], and Rīmu-x [http://oracc.museum.upenn.edu/riao/fromsamsiaddutomittanicilent18081364bc/samsiaddudynasty/rimux/index.html].[1] E. Weidner and B. Landsberger have both noted that there must have been a gap between the reigns of Išme-Dagān I and the man who the AKL records as his immediate successor, Aššur-dugul [http://oracc.museum.upenn.edu/riao/fromsamsiaddutomittanicilent18081364bc/sonsofnobody/ashurdugul/index.html]. Moreover, Landsberger suggests that those rulers were excluded from later versions of the AKL for political reasons.
Puzur-Sîn [http://oracc.museum.upenn.edu/riao/fromsamsiaddutomittanicilent18081364bc/samsiaddudynasty/puzursin/index.html], another ruler who does not appear in the AKL, states in an inscription of his that he ascended the throne in Aššur after he defeated Asīnum, the "offspring of Samsī-Addu I" (text no. 1 [http://oracc.museum.upenn.edu/riao/fromsamsiaddutomittanicilent18081364bc/samsiaddudynasty/puzursin/index.html#puzursin01]). This infers that Asīnum held authority in Aššur, but this is not certain as no inscriptions of his survive today.
[1] J. Reade has proposed that Asīnum and Rīmu-x might be one and the same person.
