When the argumentation began the young girl found herself pitted against five of the most distinguished scholars of Bologna. But she was fully equal to the occasion and passed the ordeal to which she was subjected in a manner that excited the admiration and won the plaudits of all present. Cardinal Lambertini was so impressed with the brilliant defence which she had made against the five trained dialecticians and the evidence she gave of varied and profound learning that he paid her a special visit the next day in her own home to renew his congratulations on her signal triumph and to encourage her to continue the prosecution of her studies.

In less than a month after this interesting event Laura Bassi, in response to the expressed desire of the whole of Bologna, presented herself as a candidate for the doctorate in philosophy. This was the occasion for a still more brilliant and imposing ceremony. It was held in the spacious Hall of Hercules in the Communal Palace, which was magnificently decorated for the splendid function. In addition to the distinguished personages who had been spectators of the fair student's triumph a few weeks before, there was present in the vast audience the noted French ecclesiastic, Cardinal Polignac, who was on his way from Rome to France.

The heroine of the hour, dressed in a black gown, was ushered into the great hall, preceded by two college beadles and accompanied by two of the most prominent ladies of the Bolognese nobility. She was given a seat between the chancellor and the prior of the university, who, in turn, were flanked by the professors and officials of the institution.

After the usual preliminaries of the function were over the prior of the university, Doctor Bazzani, rose and pronounced an eloquent discourse in Latin to which Laura made a suitable response in the same language. She was then crowned with a laurel wreath exquisitely wrought in silver, and had thrown round her the vajo, or university gown, both symbols of the doctorate. After this the young doctor proceeded to where the three cardinals were seated, and in delicately chosen words, also in Latin, expressed to them her thanks for the honor of their presence. All then withdrew to the apartments of the gonfalonier, where refreshments were served in sumptuous style, after which the young Laureata, accompanied by a numerous cortege and applauded by the entire city, was escorted to her home.

So profound was the impression made on the university senate by the deep erudition of Laura Bassi that it was eager to secure her services in its teaching body. But, before she could be offered a chair in the institution, long-established custom required that she should pass a public examination on the subject matter which she was to teach. Five examiners were chosen by lot, and all of them proved to be men whose names, says Fantuzzi, "will always be held by our university in glorious remembrance." They had all to promise under oath that the candidate for the chair should have no knowledge before the examination of the questions which were to be asked, and that the test of the aspirant's qualifications to fill the position sought should be absolutely free from any suspicion of favoritism or partiality.

Notwithstanding the difficulties she had to confront, Laura acquitted herself with even greater credit than on former occasions of a similar character. There was no question in the mind of any one present at the examination of the candidate's ability to fill the chair of physics, and it was, accordingly, offered to her by acclamation.

The first public lecture of the gifted young dottoressa was made the occasion of a demonstration such as the old walls of the university had rarely witnessed. Her lecture room was thronged by the élite of the city, as well as by a large class of enthusiastic students. All were charmed by her eloquence and amazed at the complete mastery she evinced of the subject she had selected for discussion. From that day forth her reputation as a scholar and a teacher was established, and her lectures were attended by appreciative students from all parts of Europe. She was especially popular with the students from Greece, Germany and Poland, and her popularity, far from waning, waxed greater with the passing years.

At the time of Laura's entering upon her professional career the senate of Bologna had a medal coined in her honor, on the obverse of which was her name and effigy, while on the reverse there was an image of Minerva, with the inscription, Soli cui fas vidisse Minervam.

Far from interrupting her studies, which had hitherto been the joy of her life, Laura's university work gave new zest to the literary and scientific pursuits which had always such a fascination for her. Among the subjects that specially engaged her attention were studies so diverse as Greek and the higher mathematics. She was particularly interested in the great physico-mathematical work of Newton, and did not rest until she had thoroughly mastered the contents of his epoch-making Principia.

A few years after she had become a member of the university faculty Laura was a European celebrity, and no one eminent by learning or birth passed through Bologna without availing himself of the opportunity of making the acquaintance of so extraordinary a woman. Men of science and letters vied with princes and emperors in doing honor to one who was looked upon by many as being, like Arete of old, endowed with a soul and a genius far above that of ordinary mortals, and as being the possessor of a talent that indicated something superhuman.
