In this paper, a proposal is made that the Anonymous Commentary to Ptolemy’s Tetrabiblos (Anon. in Ptol.) was composed not before 467 and not after 575 AD. In establishing the terminus post quem and the terminus ante quem, the Author relies on astronomical data provided by the Anonymous himself in his commentary to Ptolemy, Tetrabiblos (=Ptol. Tetr.) II.10 (p. 76, ll. 16-29 Wolf). In this passage, he reports that his master completely succeeded in interpreting the appearance of a celestial beam (δοκός) as a sign of a great loss of trunks, after which a naval battle took place where many ships were sunk; moreover, the master of the anonymous commentator predicted that the comet would remain visible until the end of Mercury’s retrogradation, and so it happened. As will be seen below, it is possible to crosscheck all this data to obtain a precise date of the comet’s appearance: 467 AD, 1 year before the naval battle of Cape Bon (468 AD). These years are also consistent with the dating that can be obtained from one of the horoscopes transmitted by the anonymous commentary (p. 98 Wolf), which corresponds to a birth that actually took place in Lower Egypt on 25 June 448 AD.

在这篇论文中，有人提议托勒密的Tetrabiblos (Anon. in Ptol .)的匿名评论不是在公元 467 年之前而不是在公元 575 年之后撰写的。在建立终点站后 quem和终点站前 quem 时，作者依赖于匿名者本人在他对托勒密的评论中提供的天文数据，Tetrabiblos (=Ptol. Tetr.) II.10 (p. 76, ll. 16-29 Wolf)。在这段经文中，他报告说他的主人完全成功地将天体光束（δοκός）的出现解释为树干大量损失的迹象，之后发生了一场海战，许多船只被击沉；而且，这位匿名评论家的大师预测，直到水星逆行结束，彗星仍然可见，所以它发生了。如下所示，可以交叉核对所有这些数据以获得彗星出现的准确日期：公元 467 年，邦角海战（公元 468 年）前一年。这些年份也与可以从匿名评论 (p. 98 Wolf) 传送的其中一个星座中获得的日期一致，这对应于公元 448 年 6 月 25 日在下埃及实际发生的出生。
