Theo Alexandrinus
Theo Alexandrinus (Graece Θέων ὁ Ἀλεξανδρεύς; Alexandriae circa annum 335 natus; ibidem circa annum 405) fuit antiquus philosophus mathematicus, astrologus Graecus, qui editionem Euclidis Elementa curavit ordinavitque, et commenta Euclidis ac Claudii Ptolemaeii operibus scripsit.

Vita 
Theon vixit et docuit Alexandriae in Aegypto saeculo quarto, cum Hypatia filia, philosophiae perita. Is appellabatur divinus, ex divina Gente Potitia, sacrorum mysteriorum Herculis Invicti sacrae scientiae, custos.

Theon nomine viri Mouseiontis in Suda memoratur, titulo ad Museum Alexandrinum pertinente, cuius rector fuit, quod a Christianis destructum est, vel, apud alios fontes, ad Serapeum cum museo confusum simili usu (secundum hos fontes, hic qui a Christianis destructum est, iuxta edictum Theodosianum, dum bibliothecae excidium vel anticipatum fuisset). Concursus inter Aurelianum et Zenobiam, reginam Palmyrensem, anno 270 fere, quem Bruchion vicus, bibliothecae sedes, destructus est vel dilatus est usque ad obsidionem Alexandriae ab Anir Ibn al-As anno 642.

Filiam habuit Hypatiam, quae prima in historia nota femina mathematice memoratur et nota est ob finem tamquam victima aliquot monachorum Christianorum (monachorum Parabolanorum).

Opera 
Maxime notus est Theo ob scholam philomathematicarum condendam.
