Overbeck received repeated solicitations to return to Germany: he was asked in 1821 by Cornelius to take the directorship of the Düsseldorf Academy, and four years later he writes in reply to the further persuasions of Wintergerst and Mosler. He urges his incapacity for the duties: he had learnt painting, he says, in a way difficult to impart to others; moreover, sculpture and architecture he did not understand at all, and as for the business matters he was without faculty. Further difficulties were the health of his wife and the welfare of his son: "every information," he continues, "I receive from my native country tells me of spiritual fermentations: the sanctuary, insufficiently protected by the law, suffers under attacks, and a proud worldly spirit raises its head and proclaims its wisdom. Can parents be blind to the risks to which they expose their child, till now reared in the most delightful simplicity of belief? Dearest friends, can you give us the assurance that we shall be able to educate our son in the simple Catholic faith which we have learnt to recognise as the most vital and consoling." Overbeck, it need hardly be added, shrank from the dangers and declined the duties. But, at length, free from pressing and onerous commissions, he lent a more willing ear to invitations from Germany. Cornelius in 1830 had come to Rome from Munich, the better to complete certain cartoons; with him were a daughter, also his wife, who had under charge Fräulein Emilie Linder, a young lady of Basle, of some means and given to pictorial pursuits. Overbeck, on the completion of his wall-painting at Assisi, rejoined the brilliant art circle of the Roman capital, and from this time dates the memorable friendship between the lady, then a Protestant, and the great Catholic painter. After a winter pleasantly passed among congenial spirits, the whole party in the early summer of 1831 set out from Rome and reached Florence. Emilie Linder returned for a time to Basle, while Overbeck, under the care of Cornelius, by way of the Tyrol reached Munich. On the news of their approach in July, the local artists, young and old, assembled at the gates, outposts had been stationed along the road, and the townfolks gathered by thousands in the streets: from afar the cheering was heard, and then group after group raised the cry, "Overbeck!" "Cornelius!" The entry soon grew into a triumphal march, and, protests notwithstanding, the horses were unyoked, and a company of lusty youths drew the carriage to the dwelling of Cornelius.
