Anonymus 33 was the father of Theophobos 1. Anonymus 33 accompanied his son when Theophobos 1 fled for refuge to the Romans during the reign of the emperor Theophilos 5: Leo Gramm. 215, Georg. Mon. Cont. 793, Ps.- Symeon 625.

According to Pseudo-Symeon he was descended from the royal Persian family; he once lived in Sinope, where the Persian rebel Babak 1, looking for a leader from the royal family, sought him out; another story was that he went to Byzantium in poverty, met a woman (Anonyma 88) who kept an inn and by her was father of Theophobos 1; after Anonymus 33 s death his son (Theophobos 1) was discovered by Babak 1, looking for a leader of royal Persian descent, and taken to the imperial palace to be reared: Ps.-Symeon 626-627 (and cf. Theophobos 1 and Theoph. Cont. III 19-20). Presumably Anonymus 33 was a Persian, like his son.

In Theophanes Continuatus there are two versions of the origins of Theophobos 1, which have features in common with the chronicle traditions recorded above; according to the one the father was a Persian of royal descent (τίς ποτε τῶν ἐκ βασιλικῆς σειρᾶς Περσῶν) who visited Constantinople on an embassy and there met a local girl on whom he fathered a son, giving him the name Theophobos before returning to Persia at the end of the embassy: Theoph. Cont. III 19 (p. 110). According to the other the father was a Persian and either a king or a member of the royal family; following a wartime reverse he fled from Persia and settled to a life of poverty in Constantinople; he entered service under a tradeswoman (καπηλίδι τινὶ γυναικῶν δουλεύοντα) with whom he eventually fell in love; they married and a son was born, Theophobos; the father died before the identity of his son became known in Persia: Theoph. Cont. III 20 (p. 111). The same two versions are recorded also in Scylitzes; see Scyl., pp. 65-66. Anonymus 33 was the father of Theophobos 1, he is also said to have lived in Sinope where he was visited by Babak 1; he was held in high honour by the Persians and was apparently a Roman official (Ῥωμαίων ὄντα τοῖς καταλόγοις): Genesius III 3.

In another version of Theophobos 1's origins, his father Anonymus 33 was a Persian of royal descent who fled to live in Constantinople in poverty; there he took service under a woman (Anonyma 88) who ran an inn; they became lovers and had a son; when their son was later discovered, aged twelve, Anonymus 33 was already dead: Genesius III 4.
