45. Projectf/r the lantern ofS. Ivo, by
cm. (Albertina, Vienna).
Four or possibly five drawings from the period just before
construction began in March 1652 show Borromini's super-
structure in its formative stages. The earliest of them is in the
Albertina, Vienna (Fig.45; see Appendix C, no.1), which I
date to the second half of 1651. It shows a large sketch plan
that clearly combines two structures, one on top of the other.
Both are climbable, though neither is anything like the final
spiral. The lantern proper has a scalloped cornice, Baalbek-
like, and triple clusters of columns on each pier, ideas that are
refined in the three sketches along the right edge of the sheet.
Two of the lantern piers are hollow and have tiny spiral stair-
cases inside; one of the sketches (top right) seems to have iron
rungs in this hollow instead of a spiral. In either case this
would be a tight climb. But on top of the lantern there is
drawn what looks like a second lantern, slightly smaller, with

THE SPIRAL OF S. IVO ALLA SAPIENZA
Aside from the Berlin drawing, there are two other images
that show the drum before Alexander VII's changes. Bar-
rikre's first known print after any Borromini building is a
small allegorical frontispiece published in 1653 with an ora-
tion in honour of S. Ivo produced by a young protege of Car-
dinal Marzio Ginetti (Fig.55; Appendix C, no.8). According
1. ~ ~ , ? ?2"t "' I IL to the allegory, the student is supposed to pass through the
Temple of Merit to get to the Temple of Honour. The former
is a conventional little shrine, but the latter is S. Ivo, with the
