'O Vesta, grant me thy favour! In thy service now I open my lips, if it is lawful for me to come to thy sacred rites. I was wrapped up in prayer; I felt the heavenly deity, and the glad ground gleamed with a purple light. Not indeed that I saw thee, O goddess (far from me be the lies of poets!), nor was it meet that a man should look upon thee; but my ignorance was enlightened and my errors corrected without the help of an instructor. They say that Rome had forty times celebrated the Parilia when the goddess, Guardian of Fire, was received in her temple; it was the work of that peaceful king, than whom no man of more god-fearing temper was born in Sabine land. The buildings which you now see roofed with bronze you might then have seen roofed with thatch, and the walls were woven of tough osiers. This little spot, which now supports the Hall of Vesta, was then the great palace of unshorn Numa. Yet the shape of the temple, as it now exists, is said to have been its shape of old, and it is based on a sound reason. Vesta is the same as the Earth; under both of them is a perpetual fire; the earth and the hearth are symbols of the home. The earth is like a ball, resting on no prop; so great a weight hangs on the air beneath it. Its own power of rotation keeps it orb balanced; it has no angle which could press on any part; and since it is placed in the middle of the world (litt. 'things') and touches no side more or less, if it were not convex, it would be nearer to some part than to another, and the universe would not have the earth as its central weight. The form of the temple is similar: there is no projecting angle in it; a dome protects it from the showers of rain. You ask why the goddess is tended by virgin ministers. Of that also I will discover the true causes. They say that Juno and Ceres were born of Ops by Saturn’s seed; the third daughter was Vesta. The other two married; both are reported to have had offspring; of the three one remained, who refused to submit to a husband. What wonder if a virgin delights in a virgin minister and allows only chaste hands to touch her sacred things? Conceive of Vesta as naught but the living flame, and you see that no bodies are born of flame. Rightly, therefore, is she a virgin who neither gives nor takes seeds, and she loves companions in her virginity. Long did I foolishly think that there were images of Vesta: afterwards I learned that there are none under her curved dome. An undying fire is hidden in that temple; but there is no effigy of Vesta nor of the fire.'- Ovid, "Fasti"
