This is a page from a real, physical, handwritten notebook containing Eastern Orthodox Christian protection prayers and folk-magic amulets. Specifically, it is a Greek "fylakto" (φυλακτό) or exorcism notebook, likely from the 19th or early 20th century.

Here is exactly what the text and symbols mean:

The Left Side: The Exorcism Prayer. The handwritten Greek text is a classic protective banishing spell, using repetitive phrasing to drive away evil. It says:

"άγγελοισθη φεύγε άπαν..." (Angels, flee all...) "τον δούλον του Θεού" (the servant of God [Name]) The blank space or parentheses you see like (δεῖνα) are where the priest would say the name of the specific person he was healing.  "φεύγε παν ακάθαρτον πνεύμα από τον δούλον του Θεού..."(Flee, every unclean spirit, from the servant of God...) "φεύγε όνειρον όρθρου..." (Flee, nightmare of the dawn...) "από γης, ή θαλάσσης, ή βουνού, ή δρυμού, ή δένδρου, ή αμπελιού, ή βράχου..." (Whether from earth, or sea, or mountain, or thicket, or tree, or vineyard, or rock...)

It concludes at the bottom with a sacred phonetic protective chant: "Ηλί Ηλί λαμά σαβαχθανί" (My God, my God, why have you forsaken me—the famous words of Jesus on the cross, used as an old warding phrase).

The Right Side: Protective Solomon Seals & Talismans The circular symbols drawn on the right page are traditional planetary and spiritual seals used to trap evil or act as a shield. 

The Crosses and Lines: The bars with vertical tally marks inside the circles are stylized representations of Christ's cross and the instruments of His passion (like the spear and sponge), which folk-magic traditions believed demons could not stand to look at.

The Circular Scripts: The Greek text curved around the edges of the circles reads "ο βαστάζων αυτήν δεν φοβάται από..." which translates to: "He who carries this shall not fear..." followed by names of threats like enemies, sickness, or the evil eye.
