So wonderful was the central circle of Minerva's web; and in the four corners were represented incidents illustrating the displeasure of the gods at such presumptuous mortals as had dared to contend with them. These were meant as warnings from Minerva to her rival to give up the contest before it was too late. But Arachne did not yield. She filled her web with subjects designedly chosen to exhibit the failings and errors of the gods. One scene represented Leda caressing the swan; and another, Danaë and the golden shower. Still another depicted Europa deceived by Jupiter under the disguise of a bull. Its appearance was that of a real bull, so naturally was it wrought and so natural the water in which it swam. With such subjects Arachne filled her canvas, wonderfully well done but strongly marking her presumption and impiety. Minerva could not forbear to admire, yet was indignant at the insult. She struck the web with her shuttle and rent it in pieces; then, touching the forehead of Arachne, she made her realize her guilt. It was more than mortal could bear; and forthwith Arachne hanged herself. "Live, guilty woman," said Minerva, "but that thou mayest preserve the memory of this lesson continue to hang, both thou and thy descendants, to all future times." Then, sprinkling her with the juices of aconite, the goddess transformed her into a spider, forever spinning the thread by which she is suspended.[82] =67. Myths of Mars.= The relations of Mars to other deities may be best illustrated by passages from the Iliad, which, generally speaking, presents him in no very favorable light. =68. Mars and Diomede.= In the war of the Greeks and the Trojans,[83] the cause of the former was espoused by Minerva, of the latter by Mars. Among the chieftains of the Greeks in a certain battle, Diomede, son of Tydeus, was prominent. Now when Mars, scourge of mortals, beheld noble Diomede, he made straight at him. ... And when they were come nigh in onset on one another, first Mars thrust over the yoke and horses' reins with spear of bronze, eager to take away his life. But the bright-eyed goddess Minerva with her hand seized the spear and thrust it up over the car, to spend itself in vain. Next Diomede of the loud war cry attacked with spear of bronze; and Minerva drave it home against Mars' nethermost belly, where his taslets were girt about him. There smote he him and wounded him, rending through his fair skin,--and plucked forth the spear again. Then brazen Mars bellowed loud as nine thousand warriors or ten thousand cry in battle as they join in strife and fray. Thereat trembling gat hold of Achæans and Trojans for fear, so mightily bellowed Mars insatiate of battle. [Illustration: FIG. 53. ATHENA]
