The second Aldine Anchor, 1519-1524. Last appearing in this form on the "Homer" of 1524, the first anchor being again used from 1524 to 1540.
From the year 1524 to 1529, when Torresano died, an exact copy of the first anchor was again employed and continued to be so used until 1540, when Paulus Manutius, the son of Aldus, took exclusive possession of his father's business. It will be noted that during the three years following the death of Torresano (1530-31-32) no books were issued from the press; and when it recommenced operations in 1533, it was for the benefit of Paulus Manutius and the representatives of Torresano "In ædibus hæredum Aldi Manutii et Andreæ Asulani soceri". In 1540, as before stated, Paulus Manutius took entire control of the business, and a third variation of the anchor was introduced, the inscription on the title-pages being "apud Aldi Filios".
The third Aldine Anchor, 1540-1546, called the Ancora grassa.
The fourth Aldine Anchor, 1546-1554.
From 1546 to 1554 yet another variation of the anchor was adopted, sometimes without the surrounding device. In 1555 a slight modification of the third anchor, surrounded sometimes with scroll work, came into fashion again, and so continued until the death of Paulus Manutius on the 6th of April, 1574.
