[2] Bernhardy, recognizing this expression as Homeric (see next note), attributed this material to an unknown scholion (scholio cuidam). The source which the phrase h(=| a)\n o( toiou=tos bro/tos e)gge/nhtai stems from is Plato, Republic 566D; there, however, modern editions construe the noun not as bro/tos ("blood, gore") but differently-accented broto/s ("mortal"), and the phrase as a whole becomes "the city where such a mortal would have been born". Thus, the passage can easily be understood if the word bro/ton is integrated after e)gge/nhtai. It is also possible that two different entries have been combined here, one concerning "the thirtieth day of the month", the other related to the words e)n h(=|.
*nu=n as an equivalent of "in the present instance" or "in the example above" is common in scholia.
[3] For this expression see Homer, Iliad 7.425, 14.7, 18.345 [schol. ad loc.: bro/ton ai(mato/enta: to\ u(po\ tou= fo/nou ai(=ma]; 23.41 [with schol. Il. 23.41a2].
