[1] This neuter noun has the same or similar glossing in other lexica. Latte on Hesychius s.v. considers it quoted from Euripides, Phoenician Women 23; it is certainly tragedic vocabulary.
[2] Again, same equivalence in other lexica, including Photius. The noun in question has now become feminine a)mplaki/a and the glossing noun a(marti/a -- both indicating propensities rather than acts. This dative plural a)mplaki/ais is probably quoted from Euripides, Hippolytus 146.
[3] This passage is taken (with minor changes) from Diogenes Laertius 7.120-1, where the Stoic thesis that all faults or moral mistakes are equal (cf. alpha 2479, end; kappa 320, end) is quoted and discussed. According to Diogenes' report, this is what Chrysippus said, in the fourth book of his treatise Ethical Investigations, as well as Perseus and Zeno himself, the founder of the school.
[4] On the coast of Egypt, east of Alexandria.
[5] The sense of the assertion (repeated in part at kappa 320) is explained, to some extent, in the Diogenes Laertius text and in a passage contained in Stobaeus (Eclogae, 2. 106, 21-107, 9, ed. Wachsmuth): he who makes a larger moral error and he who makes a smaller one are both acting incorrectly. All moral mistakes are equal (isa) but are not similar (homoia), i.e. they are not qualitatively similar. Just as there are no degrees of falsehood, so too there are no degrees of incorrect acts. For a detailed treatment of the issue see Rist (below) 81-96, and Annas (below) 407-411.
[6] Disciple of the Stoic Antipater of Tarsus (second century BCE), successor to Diogenes of Babylon as head of the Stoic school. The thesis that not all the moral mistakes are equal was maintained both by Heraclides of Tarsus and Athenodorus (see Diogenes Laertius, 7.121).
