PALLAS:1)https://en.wikipedia.org/wiki/Giants_(Greek_mythology). According to Apollodorus, he was flayed by Athena, who used his skin as a shield.2)Apollodorus, 1.6.2. Other accounts name others whose hyde provided Athena’s aegis:3)Robertson, Noel, p. 42. the epic poem Meropis has Athena kill and flay the Giant Asterus [see Asterius above] while Euripides‘ Ion has Gorgon, here considered to be a Giant, as Athena’s victim.4)Euripides, Ion 987–997. Claudian names him as one of several Giants turned to stone by Minerva’s Gorgon shield.5)Claudian, Gigantomachia 91–103 (pp. 286–289).))
Pallas:((http://greekmythology.wikia.com/wiki/Pallas_(Gigantes). was one of the Gigantes. Athena crushed him with a stone and flayed him in order to use his skin to make her as a shield. Since no Gigantes could be killed by a god without the aid of a mortal hero, it can be assumed that Herakles assisted Athena in killing Pallas though it is not stated.
