Plutarch Quaestiones Convivales 5.3.3

[3] But Lucanius, with a smile looking upon me, cried out: Good God! here’s a deal of learning. But others have taken advantage of our ignorance and unacquaintedness with such matters, and, on the contrary, persuaded us that the pine was the first garland, and that afterwards in honor of Hercules the parsley was received from the Nemean games, which in a little time prevailing, thrust out the pine, as if it were its right to be the wreath; but a little while after the pine recovered its ancient honor, and now flourishes in its glory. I was satisfied, and upon consideration found that I had met with a great many authorities for it. Thus Euphorion writes of Melicertes, And Callimachus is plainer and more express, when he makes Hercules speak thus of parsley, And beside, if I am not mistaken, in Procles’s history of the Isthmian games I met with this passage; at first a pine garland crowned the conqueror, but when this game began to be reckoned amongst the sacred, then from the Nemean solemnity the parsley was received. And this Procles was one of Xenocrates’s fellow-students at the Academy.
