There is an old legend in Lucerne that at this period the elder Holbein was living in the town with his two sons, but it does not appear to have any foundation in fact.[133] There is much more probability that Ambrosius accompanied Hans, or followed him shortly afterwards, and remained for some time at work with his brother on the Hertenstein house; though here again there is no actual record of such an absence from Basel. There is, however, a fine drawing by him in the Basel Gallery (No. 297), a half-length figure of a young man of the Von Rüdiswiler family,[134] which is thought to afford some proof that Ambrosius was in Lucerne at the time, for the Rüdiswiler family was one of the most important in the district, their chief seat being at Rüdiswil. Members of this house were settled both in Lucerne and Solothurn, and it is supposed that Ambrosius drew the portrait of this youth of patrician birth in the former town during 1517. The sitter is shown in profile, in a heavy brown cloak, wearing his cap on the side of his head. His fair straight hair covers his ears, and he holds a large red heart in his hand. The drawing has at some time been cut out round the outline and mounted on parchment, and the inscription in secret cipher, below the coat of arms, had been copied at the same time from the one which existed on the original drawing before the cutting out took place. Ambrosius, however, must have been back again in Basel by the summer of 1518, for in that year, on June 6, he purchased his right of citizenship. The first mention of him in the town books is on September 26, 1516, when “Ambrosy Holbein von augspurg, ein maler,” appeared in court as a witness in a libel action brought by Bastian Lepzelter, the sculptor, against a tailor, Andreas Huber, for insulting remarks made on the previous 25th of July, when the plaintiff, Ambrosius, and another friend, were enjoying themselves in the house of Hans Herbster.[135] Ambrosius may perhaps have been working as a journeyman under Herbster at the time. He joined the Painters’ Guild “zum Himmel,” to which bakers, saddlers, and barber-surgeons also belonged, on St. Matthias’ Day, February 24, 1517. The entry in the book of the guild runs as follows: “Item es hatt entpfangen die zunfft vff sant Mattistag ambross Holbein maler von augspurg In dem xvii Jor.” According to an order of the Basel Council issued in 1487, any one entering a guild was obliged to take oath to purchase the freedom of the city within a month. This Ambrosius did not do until the following year, which possibly indicates that he left the town shortly after joining the guild, early in 1517, without fulfilling his obligations. It may be that he had not sufficient money for the payment of the fees, for when, on June 6, 1518, he became a burgher, he was only able to find one gulden out of the four which were required, Jörg Schweiger, the goldsmith, whose portrait, now in the Basel Gallery (No.
