Αφότου ο Μέγας Κωνσταντίνος ίδρυσε την αυτοκρατορική βιβλιοθήκη, άρχισαν να εμφανίζονται και άλλοι τύποι βιβλιοθηκών. Οι βιβλιοθήκες της Βυζαντινής Αυτοκρατορίας μπορούν να ομαδοποιηθούν σε τέσσερις κατηγορίες: αυτοκρατορική, πατριαρχική, μοναστική και ιδιωτική (Papademetriou, 2000, p. 171). Εκτός από αυτούς τους τέσσερις τύπους βιβλιοθηκών που αναγνωρίστηκαν από τους ιστορικούς, πρόσθεσα και μια πέμπτη: την πανεπιστημιακή βιβλιοθήκη που ανήκε στο πανεπιστήμιο της Κωνσταντινούπολης, το οποίο ιδρύθηκε το 425 μ.Χ., από τον αυτοκράτορα Θεοδόσιο Β ‘(408-450) (Drîmba, 1999, p. 215). Θα παρουσιάσουμε περαιτέρω και θα συζητήσουμε τον καθένα από τους πέντε τύπους βιβλιοθηκών που αναφέρονται παραπάνω, ξεκινώντας από την αυτοκρατορική βιβλιοθήκη.

Parents’ brain activity ‘echoes’ their infant’s brain activity when they play together
When infants are playing with objects, their early attempts to pay attention to things are accompanied by bursts of high-frequency activity in their brain. But what happens when parents play together with them? New research, publishing December 13 in the open-access journal PLOS Biology, by Dr Sam Wass of the University of East London in collaboration with Dr Victoria Leong (Cambridge University and Nanyang Technological University, Singapore) and colleagues, shows for the first time that when adults are engaged in joint play together with their infant, their own brains show similar bursts of high-frequency activity. Intriguingly, these bursts of activity are linked to their baby’s attention patterns and not their own.

Paradise and Hell according to Orthodox tradition
By Protopresbyter George Metallinos, Dean of the Athens University School of Theology
On the Last Sunday of Lent “we commemorate the Second and Incorruptible Coming of our Lord Jesus Christ”. The expression “we commemorate” of the Book of Saints confirms that our Church, as the Body of Christ, re-enacts in its worship the Second Coming of Christ as an “event” and not just something that is historically expected. The reason is, that through the Divine Eucharist, we are transported to the celestial kingdom, to meta-history. It is in this orthodox perspective, that the subject of paradise and hell is approached. Continue reading “Paradise and Hell according to Orthodox tradition”
