^As recorded by a calendar inscription known as the Fasti Verulani (c. 17–37 AD) for 14 January = Degrassi, Inscriptiones Italiae 13.2.397–98, as cited by Jerzy Linderski and Anna Kaminska-Linderski, "The Quaestorship of Marcus Antonius," Phoenix 28.2 (1974), p. 217, note 24. The religious prohibition placed by Augustus on the day, marked as a dies vitiosus ("defective" day), is explained by Linderski, "The Augural Law", Aufstieg und Niedergang der römischen Welt II.16 (1986), pp. 2187–88. 14 January is accepted as Antony's birthday also by C.B.R. Pelling, Plutarch: Life of Antony (Cambridge University Press, 1988), p. 299, commentary to 73.5; Nikos Kokkino, Antonia Augusta (Routledge, 1992), p. 11; Pat Southern, Mark Antony (Tempus, 1998), p. ii; n.p.. According to 11.3), the emperor Claudius, Antony's grandson through maternal lineage, evaded the prohibition on commemorating Antony's birthday by calculations showing that had he been born under the Julian calendar he would have shared his birthday with Drusus, the emperor's father. Drusus was born in late March or early April, based on a reference that he was born "within the third month" after his mother Livia married Augustus on 17 January; G. Radke, "Der Geburtstag des älteren Drusus," Wurzburger Jahrbucher fur die Altertumswissenschaft 4 (1978), pp. 211–13, proposed that a birth date of 28 March for Drusus would resolve the chronological difficulties. Radke's proposal is summarized in English by the p. 106, and by Marleen B. Flory, "The Symbolism of Laurel in Cameo Portraits of Livia," in Memoirs of the American Academy in Rome (University of Michigan Press, 1995), vol. 40, p. 56, note 48.
^Cicero is the only ancient source to mention a first marriage to an otherwise unknown Fadia (Philippics, XIII, 10)
^Ancient writers (e.g. Appian, Civil Wars 5.8.1) place the beginning of their famous romance at this meeting with Antony totally surrendering to Cleopatra's beauty but modern historians reject this notion as retrospective historical propaganda on the part of Augustus.
^Lepidus, though still a member of the Triumvirate, was relegated to a junior position within the three-man dictatorship as Antony and Octavian established themselves.
^It is also speculated that Antony's legions, composed largely of Caesarian veterans, did not wish to fight the adoptive son of their former general.
^After celebrating his triumph, Ventidius disappears from the historical record.
