Print edition: multiple text re-uses of the same information

The same information deriving from a lost work may be quoted and re-used by different authors in similar or different ways. These authors are usually referred to as "witnesses to lost texts".


1) The first screenshot shows an example of witnesses of the same information deriving from a lost work of Istros. References to these authors are printed in the section  "witnesses and loci paralleli", which includes not only witnesses but also information about other (parallel) sources quoted in the same context that preserves the information about Istros.


The first source to quote Istros is Harpocration in his Lexicon of the Ten Orators (s.v. Παναθήναια):

Panathenaia: Demosthenes in the Philippics (4.35). The Panathenaia held at Athens was two-fold, one festival being held annually, and the other celebrated every five years, the latter also called the Great Panathenaia. Isocrates in the Panathenaichus (12.17) says "a short time before the Great Panathenaia". The first to conduct the festival was Erichthonius, son of Hephaistos, according to the reports of Hellanicus and Adrotion, both in the first book of the Atthis (FHG I 54 fr. 65 = FHG I 371 fr. 1). Before his time the festival was called the Athenaia, as Istros makes clear in the third book of his Attika.


The text of Harpocration has been reproduced in an abdridged form by Photius in the Lexicon (Π 376) and by the Suda (Π 152): 

Δημοσθένης Φιλιππικοῖς. διττὰ Παναθήναια ἤγετο Ἀθήνησι, τὰ μὲν καθ' ἕκαστον ἐνιαυτὸν, τὰ δὲ διὰ πεντετηρίδος, ἅπερ καὶ μεγάλα ἐκάλουν. Ἰσοκράτης Παναθηναϊκῷ φησι μικρὸν δὲ πρὸ τῶν μεγάλων Παναθηναίων. ἤγαγε δὲ τὴν ἑορτὴν πρῶτος Ἐριχθόνιος ὁ Ἡφαίστου, καθά φησιν Ἑλλάνικός τε καὶ Ἀνδροτίων, ἑκάτερος ἐν Ἀτθίδος. πρὸ τούτου δὲ Ἀθήναια ἐκαλεῖτο, ὡς δεδήλωκεν Ἴστρος ἐν γ τῶν Ἀττικῶν.
Photius, Lexicon (Π 376) 
Παναθήναια: ἀγὼν πεντετηρικὸς Ἀθήνησιν.
Suda (Π 152)
Παναθήναια: διττὰ Παναθήναια ἤγετο Ἀθήνησι, τὰ μὲν καθ' ἕκαστον ἐνιαυτόν, τὰ δὲ διὰ πενταετηρίδος, ἃ καὶ μεγάλα ἐκάλουν. ἤγαγε δὲ τὴν ἑορτὴν πρῶτος Ἐριχθόνιος ὁ Ἡφαίστου. τὰ δὲ Παναθήναια πρότερον Ἀθήναια ἐκαλοῦντο.


Finally, the text of Harpocration refers to other parallel sources that dealt with the same topic treated by Istros: Demosthenes (4.35), Isocrates (12.17), and the two Atthidographers Hellanicus and Androtion (FHG I 54 fr. 65 = FHG I 371 fr. 1), whose texts are lost.


2) The second screenshot shows an example of two text re-uses of an information drawn from Istros by two different sources: the scholia (or comments) to Sophocles' Oedipus at Colonus 1053 (Berti F 22a) and the scholia to Lycophron's Alexandra 1328 (Berti F 22b).
