The title compound, C19H23N2+·ClO4−, also known as LDS 698, contains almost parallel pyridyl and phenyl ring systems and an in‐plane di­methyl­amino group. The extended pyridyl amino­ethyl group is nearly perpendicular to the dimethyl­amino group. The mol­ecules stack along the a axis, with the ring systems oblique to this axis.

There are two mol­ecules in the asymmetric unit of the title compound, C22H33BF2N2, also known as Pyrromethene 580. The dihedral angle between the least squares planes of the bora‐s‐indacene rings of the two molecules (A and B) is 80.2 (6)°. The F atoms extend an average distance of 1.127 (6) Å (in A) and 1.230 (2) Å (in B) from the mean plane deviation of this ring [0.024 (4) Å in A and 0.018 (2) Å in B]. The dihedral angle between the mean planes of the bora‐s‐indacene rings of each mol­ecule is 80.2 (6)°.

This paper addresses the issue of the historicity of another, older son of P. Quinctilius Varus who is attested in Joseph. AJ 17.288, but not in the parallel version at BJ 2.68. Modern scholarship, as evidenced by Ladislav Vidman (1998) and Klaus Wachtel (1999), finds itself at a loss as to which opinion, that of Walther John (1958) or of Meyer Reinhold (1972), to support. Whereas John rejects the evidence for an older son of Varus in AJ and proposes L. Nonius Asprenas (cos. suff. 6 CE) instead, Reinhold tersely rebuts John, supporting the validity of the text. This article examines the textual and prosopographical bases upon which scholars have built their cases for and against the existence of an older son of Varus. In the process, it is shown that there is greater reason to take the evidence for another son of Varus at face value than to follow John's problematic argument, and further, that Reinhold's article left unexamined significant details upon which his argument needed to be built.
